    Cold and Hot Nuclear Matter Effects on Charmonium Production in p+Pb Collisions at LHC Energy

    Baoyi Chen · Tiecheng Guo · Yunpeng Liu · Pengfei Zhuang🇨🇳

    We study cold and hot nuclear matter effects on charmonium production in p+Pb collisions at TeV in a transport approach. At the forward rapidity, the cold medium effect on all the states and the hot medium effect on the excited states only can explain well the and yield and transverse momentum distribution measured by the ALICE collaboration, and we predict a significantly larger broadening in comparison with . However, we can not reproduce the and data at the backward rapidity with reasonable cold and hot medium effects.

    Elastic Coulomb breakup of Na

    G. Singh (IITR) · Shubhchintak (TAMUC) · R. Chatterjee (IITR)

    Purpose : The aim of this paper is to study the elastic Coulomb breakup of Na on Pb to give us a core of Na with a neutron and in the process we try and investigate the one neutron separation energy and the ground state configuration of Na. Method : A fully quantum mechanical Coulomb breakup theory within the architecture of post-form finite range distorted wave Born approximation extended to include the effects of deformation is used to research the elastic Coulomb breakup of Na on Pb at 100 MeV/u. The triple differential cross-section calculated for the breakup is integrated over the desired components to find the total cross-section, momentum and angular distributions as well as the average momenta, along with the energy-angular distributions. Results : The total one neutron removal cross-section is calculated to test the possible ground state configurations of Na. The average momentum results along with energy-angular calculations indicate Na to have a halo structure. The parallel momentum distributions with narrow full widths at half maxima signify the same. Conclusion : We have attempted to analyse the possible ground state configurations of Na and in congruity with the patterns in the `island of inversion' conclude that even without deformation, Na should be a neutron halo with a predominant contribution to its ground state most probably coming from Na() configuration. We also surmise that it would certainly be useful and rewarding to test our predictions with an experiment to put stricter limits on its ground state configuration and binding energy.
