Constraining the anisotropy of the Universe with the Pantheon supernovae sample
2019, 43(12): 125102. doi: 10.1088/16741137/43/12/125102We test the possible dipole anisotropy of the Finslerian cosmological model and the other three dipolemodulated cosmological models, i.e. the dipolemodulated ΛCDM, wCDM and Chevallier–Polarski–Linder (CPL) models, by using the recently released Pantheon sample of SNe Ia. The Markov chain Monte Carlo (MCMC) method is used to explore the whole parameter space. We find that the dipole anisotropy is very weak in all cosmological models used. Although the dipole amplitudes of four cosmological models are consistent with zero within the
$1\sigma$ uncertainty, the dipole directions are close to the axial direction of the plane of the SDSS subsample in Pantheon. This may imply that the weak dipole anisotropy in the Pantheon sample originates from the inhomogeneous distribution of the SDSS subsample. A more homogeneous distribution of SNe Ia is necessary to constrain the cosmic anisotropy. 
QCD analysis of CMS W + charm measurements at LHC with
${\sqrt { s} = 7\; {\bf{TeV}}}$ and implications for strange PDF2019, 43(12): 123101. doi: 10.1088/16741137/43/12/123101We calculate crosssections and crosssection ratios of a charm quark production in association with a W gauge boson at nexttoleading order QCD using MadGraph and CT10NNLO, CT14NNLO, and MSTW2008NNLO PDFs. We compare the results with measurements from the CMS detector at the LHC at a centerofmass energy of 7 TeV. Moreover, we calculate absolute and normalized differential crosssections as well as differential crosssection ratios as a function of the lepton pseudorapidity from the W boson decay. The correlation between the CT14NNLO PDFs and predictions for$W+$ charm data are studied as well. Furthermore, by employing the error PDF updating method proposed by the CTEQTEA group, we update CT14NNLO PDFs, and analyze the impact of CMS 7 TeV$W+$ charm production data to the original CT14NNLO PDFs. By comparison of the$g(x,Q)$ ,$s(x,Q)$ ,$u(x,Q)$ ,$d(x,Q)$ ,$\bar u(x,Q)$ , and$\bar d(x,Q)$ PDFs at$Q=1.3$ GeV and$Q = 100$ GeV for the CT14NNLO and CT14NNLO+Wc, we see that the error band of the$s(x,Q)$ PDF is reduced in the region$x<0.4$ , and the error band of$g(x,Q)$ PDF is also slightly reduced at region$0.01 < x<0.1$ . 
Microscopic study of electromagnetic properties and band spectra of neutron deficient ^{133,135,137}Sm
2019, 43(12): 124108. doi: 10.1088/16741137/43/12/124108A microscopic high spin study of neutron deficient and normally deformed ^{133,135,137}Sm has been carried out in projected shell model framework. The theoretical results have been obtained for the spins, parities and energy values of yrast and excited bands. Besides this, the band spectra, band head energies, moment of inertia and electromagnetic transition strengths are also predicted in these isotopes. The calculations successfully give a deeper understanding of the mechanism of the formation of yrast and excited bands from the single and multiquasi particle configurations. The results on moment of inertia predict an alignment of a pair of protons in the proton (1h_{11/2})^{2} orbitals in the yrast ground state bands of ^{133137}Sm due to the crossing of one quasiparticle bands by multiquasiparticle bands at higher spins. The discussion in the present work is based on the deformed single particle scheme. Any future experimental confirmation or refutation of our predictions will be a valuable information which can help to understand the deformed single particle structure in these odd mass neutron deficient ^{133137}Sm.

Mass spectra and wave functions of the doubly heavy baryons with J^{P}=1^{+} heavy diquark cores
Published: 20191213, doi: 10.1088/16741137/44/1/013102Show AbstractMass spectra and wave functions of the doubly heavy baryons are computed assuming that the two heavy quarks inside a baryon form a compact heavy ‘diquark core’ in a color antitriplet, and bind with the remaining light quark into a colorless baryon. The two reduced twobody problems are described by the relativistic BetheSalpeter equations (BSEs) with the relevant QCD inspired kernels. We focus on the doubly heavy baryons with
$1^+$ heavy diquark cores. After solving BSEs in the instantaneous approximation, we present the mass spectra and the relativistic wave functions of the diquark cores, and of the lowlying baryon states$J^P=\frac{1}{2}^+$ and$\frac{3}{2}^+$ with flavors$(ccq)$ ,$(bcq)$ and$(bbq)$ . A comparison with other approaches is also made. 
Isotopic crosssections in proton induced spallation reactions based on the Bayesian neural network method
Published: 20191211, doi: 10.1088/16741137/44/1/014104Show AbstractThe Bayesian neural network (BNN) method is proposed to predict the isotopic crosssections in proton induced spallation reactions. Learning from more than 4000 data sets of isotopic crosssections from 19 experimental measurements and 5 theoretical predictions with the SPACS parametrization, in which the mass of the spallation system ranges from 36 to 238, and the incident energy from 200 MeV/u to 1500 MeV/u, it is demonstrated that the BNN method can provide good predictions of the residue fragment crosssections in spallation reactions.

Predictions of
${\Upsilon{(4S) }\to {h_b(1P,2P) \pi^+\pi^}}$ transitionsPublished: 20191206, doi: 10.1088/16741137/44/2/023103Show AbstractWe study the contributions of intermediate bottomoniumlike$Z_b$ states and the bottom meson loops in the heavy quark spin flip transitions$\Upsilon(4S) \to h_b(1P,2P) \pi^+\pi^$ . Depending on the constructive or destructive interferences between the$Z_b$ exchange and the bottom meson loops mechanisms, we predict two possible branching ratios for each process: BR$_{\Upsilon(4S) \to h_b(1P)\pi^+\pi^}\simeq\big(1.2^{+0.8}_{0.4}\times10^{6}\big)$ or$\big( 0.5^{+0.5}_{0.2}\times10^{6}\big)$ , and$ {{BR}}_{\Upsilon(4S) \to h_b(2P)\pi^+\pi^}\simeq \big(7.1^{+1.7}_{1.1}\times10^{10}\big)$ or$\big( 2.4^{+0.2}_{0.1}\times10^{10}\big)$ . The contribution of the bottom meson loops is found to be considerably larger than that of the$Z_b$ exchange in the$\Upsilon(4S) \to h_b(1P) \pi\pi$ transitions, while its decay rates are not comparable to those of heavy quark spin conserved$\Upsilon(4S) \to \Upsilon(1S,2S) \pi\pi$ processes. We also predict the contribution of the charm meson loops in the branch fractions of$\psi(3S,4S) \to h_c(1P)\pi\pi$ .
