Search for hidden-charm tetraquark with strangeness in Ablikim, M., Achasov, M.N., Adlarson, P., ... more(574) IOP 2023-03-01 We report a search for a heavier partner of the recently observed $ Z_{cs}(3985)^{-} $ state, denoted as $ Z_{cs}(3985)^{-} $ , in the process $ Z_{cs}(3985)^{-} $ , based on $ Z_{cs}(3985)^{-} $ collision data collected at the center-of-mass energies of $ Z_{cs}(3985)^{-} $ , 4.682 and 4.699 GeV with the BESIII detector. The $ Z_{cs}(3985)^{-} $ is of interest as it is expected to be a candidate for a hidden-charm and open-strange tetraquark. A partial-reconstruction technique is used to isolate $ Z_{cs}(3985)^{-} $ recoil-mass spectra, which are probed for a potential contribution from $ Z_{cs}(3985)^{-} $ ( $ Z_{cs}(3985)^{-} $ ). We find an excess of $ Z_{cs}(3985)^{-} $ ( $ Z_{cs}(3985)^{-} $ ) candidates with a significance of $ Z_{cs}(3985)^{-} $ , after considering systematic uncertainties, at a mass of $ Z_{cs}(3985)^{-} $ . As the data set is limited in size, the upper limits are evaluated at the 90% confidence level on the product of the Born cross sections ( $ Z_{cs}(3985)^{-} $ ) and the branching fraction ( $ Z_{cs}(3985)^{-} $ ) of $ Z_{cs}(3985)^{-} $ , under different assumptions of the $ Z_{cs}(3985)^{-} $ mass from 4.120 to 4.140 MeV and of the width from 10 to 50 MeV at the three center-of-mass energies. The upper limits of $ Z_{cs}(3985)^{-} $ are found to be at the level of $ Z_{cs}(3985)^{-} $ pb at each energy. Larger data samples are needed to confirm the $ Z_{cs}(3985)^{-} $ state and clarify its nature in the coming years.

Static properties and semileptonic transitions of lowest-lying double heavy baryons Ghalenovi, Zahra, Moazzen Sorkhi, Masoumeh IOP 2023-03-01 The static properties and semileptonic decays of ground-state doubly heavy baryons are studied in the framework of a non-relativistic quark model. Using a phenomenological potential model, we calculate the ground-state masses and magnetic moments of doubly heavy Ω and Ξ baryons. In the heavy quark limit, we introduce a simple form of the universal Isgur-Wise function used as the transition form factor and then investigate the exclusive $ b \rightarrow c $ semileptonic decay widths and branching fractions for $ b \rightarrow c $ baryon transitions. Our obtained results are in agreement with other theoretical predictions.

Next-to-leading-order QCD corrections to gluon fragmentation into Quarkonia Feng, Feng, Jia, Yu IOP 2023-03-01 Within the NRQCD factorization framework, we compute the next-to-leading-order QCD corrections to the gluon fragmentation into the $ {}^1S_0^{(1,8)} $ Fock components of a quarkonium, at the lowest order in velocity expansion. We follow the operator definition of the fragmentation function advanced by Collins and Soper. The key technique underpinning our calculation is the sector decomposition method widely used in the area of multi-loop computation. It is found that the NLO QCD corrections have significant effects, and qualitatively modify the profiles of the corresponding leading-order fragmentation functions.

What can we learn from the total width of the Higgs boson? Cao, Qing-Hong, Li, Hao-Lin, Xu, Ling-Xiao, ... more(4) IOP 2023-03-01 As one of the key properties of the Higgs boson, the Higgs total width is sensitive to the global profile of the Higgs boson couplings, and thus new physics would modify the Higgs width. We investigate the total width in various new physics models, including various scalar extensions, composite Higgs models, and the fraternal twin Higgs model. Typically, the Higgs width is smaller than the standard model value due to mixture with other scalars if the Higgs is elementary, or curved Higgs field space for the composite Higgs. On the other hand, except for the possible invisible decay mode, the enhanced Yukawa coupling in the two Higgs doublet model or the exotic fermion embeddings in the composite Higgs could enhance the Higgs width greatly. The precision measurement of the Higgs total width at the high-luminosity LHC can be used to discriminate certain new physics models.

Chiral symmetry restoration and properties of Goldstone bosons at finite temperature Xu, Yin-Zhen, Qin, Si-Xue, Zong, Hong-Shi... more(3) IOP 2023-03-01 We study chiral symmetry restoration by analyzing thermal properties of QCD's(pseudo-) Goldstone bosons, especially the pion. The meson properties are obtained from the spectral densities of mesonic imaginary-time correlation functions. To obtain the correlation functions, we solve the Dyson-Schwinger equations and the inhomogeneous Bethe-Salpeter equations in the leading symmetry-preserving rainbow-ladder approximation. In chiral limit, the pion and its partner sigma degenerate at the critical temperature $T_{\rm c}$ . At $T_{\rm c}$ , it was found that the pion rapidly dissociates, which signals deconfinement phase transition. Beyond the chiral limit, the pion dissociation temperature can be used to define the pseudo-critical temperature of the chiral phase crossover, which is consistent with that obtained by the maximum point of chiral susceptibility. A parallel analysis for kaon and pseudoscalar $T_{\rm c}$ suggests that heavy mesons may survive above $T_{\rm c}$ .

Linking anomalies to Hubble tension via a single right-handed neutrino Duan, Wen-Feng, Li, Shao-Ping, Li, Xin-Qiang, ... more(4) IOP 2023-03-01 Updated measurements from the LHCb and SH0ES collaborations have respectively strengthened the deviations of the ratio $R_{K}$ in rare semi-leptonic $R_{K}$ -meson decays and the present-day Hubble parameter $R_{K}$ in the Universe, implying tantalizing hints of new physics beyond the standard model. In this paper, we consider a simple flavor-specific two-Higgs-doublet model, where long-standing $R_{K}$ anomalies can be addressed by a one-flavor right-handed neutrino. An intriguing prediction resulting from the parameter space for the $R_{K}$ resolution under flavor- and collider-physics constraints points toward a shift in the effective neutrino number, $R_{K}$ , as a favored way to ease the $R_{K}$ tension. Depending on whether the neutrino is of the Dirac or Majorana type, we show that the resulting shift is $R_{K}$ for the former case and $R_{K}$ for the latter case. While the Dirac case is disfavored by the CMB polarization measurements, the Majorana solution is consistent with recent studies using a combined dataset from various sources. Consequently, such a simple flavor-specific two-Higgs-doublet model provides a link between $R_{K}$ anomalies and $R_{K}$ tension, which in turn can be readily verified or disproved by upcoming measurements.

Introduction to Policing in the Pacific Watson, Danielle, Howes, Loene, Dinnen, Sinclair, ... more(5) Springer 2023-02-08 {p=Research on policing in the Pacific Islands draws from multiple disciplines, reflecting the multifaceted nature of policing in local contexts that neither fit a Western model of statehood nor adopt an analytic position from the global North. This chapter sets the scene for a focused, contextualised and interdisciplinary discussion of policing in Pacific Islands countries and territories. It recognises the need to analyse policing both within the broader context of the global dynamics of policing, crime and (in)security, and within the specific, complex, and diverse countries and territories of the region. The chapter outlines the structure of the book and provides an overview of the chapters that follow., h1=Abstract}

School Experience Students’ Perspective on the Benefit of Blackboard LMS for e-Portfolio Development Nkonki, V., Tsipa-Booi, N., Mqukuse, B., ... more(4) Springer 2023-02-08 {p=Putting together a Portfolio of evidence is a difficult, time-consuming, and intimidating undertaking, especially when emergency remote online teaching and learning is required as compelled by COVID-19 restrictions. Under these conditions, student teachers were required to finish their school experience teaching practice and provide portfolios of evidence to demonstrate their developing teaching competencies. Given that there were no contact lectures or tutorials during this time, these students had to rely on Blackboard support through online workshops and pre-recorded training sessions to help them construct their school experience e-portfolios. The aim of this study was to evaluate how Blackboard support equipped the student teachers to develop their e-portfolios with no face-to-face contact sessions. This study examined the benefits of Blackboard support in the building of e-Portfolios by student teachers. The fourth-year and Post-Graduate Certificate in Education (PGCE) students submitted data through a qualitative survey in which they narratively conveyed their perspectives on support provided for e-portfolios. Thematic analysis was used to extract meaning units, which were then aggregated into themes and then presented as categories suggested by the research questions. This study evaluates Blackboard support as well as the affordances that are most and least attended achieved with the Blackboard e-Portfolio module, and through the support provided by the workshop facilitators. Recommendations on the effective use of Blackboard, the practices that would foster the realisation of all the conceptual, practical and reflective competencies and the enhancement of e-Portfolio development for the school experience are provided., h1=Abstract}
