    Reply to Comment on "Six-body bound system calculations in the case of effective Alpha-core structure"

    Eskandar Ahmadi Pouya · Ali Akbar Rajabi

    The present paper is provided in response to the comment of M. R. Hadizadeh et.al on our original paper Six-body bound system calculations in the case of effective Alpha-core structure [Eur. Phys. J. Plus (2016) 131: 240].In this paper we have presented our clarifications on their arguments about of the accuracy of the procedure of the calculations. In this paper our arguments turn out to be very efficient mainly discussed from the authors misunderstanding of the issues discussed in the original paper. In fact, their comment aims to exaggeratedly show that our paper is poor,but our following statements demonstrate that their comment is misleading and consequently unacceptable.

    Investigating the quark flavor dependence of the chiral magnetic effect with a multiphase transport model

    Ling Huang🇨🇳 · Chun-Wang Ma🇨🇳 · Guo-Liang Ma🇨🇳

    Because the properties of the QCD phase transition and the chiral magnetic effect (CME) depend on the number of quark flavors () and quark mass, relativistic heavy-ion collisions provide a natural environment to investigate the flavor features if quark deconfinement occurs. We introduce an initial two-flavor or three-flavor dipole charge separation into a multiphase transport (AMPT) model to investigate the flavor dependence of the CME. By taking advantage of the recent ALICE data of charge azimuthal correlations with identified hadrons, we attempt to disentangle two-flavor and three-flavor CME scenarios in Pb+Pb collisions at 2.76 TeV. We find that the experimental data show a certain potential to distinguish the two scenarios, therefore we further suggest to collect more data to clarify the possible flavor dependence in future experiments.

    Neutrino-Oxygen CC0 scattering in the SuSAv2-MEC model

    G.D. Megias🇪🇸 · M.B. Barbaro🇮🇹 · J.A. Caballero🇪🇸 · J.E. Amaro🇪🇸 · T.W. Donnelly🇺🇸 · I. Ruiz Simo🇪🇸 · J. W. Van Orden🇺🇸

    We present the predictions of the SuSAv2-MEC model for the double differential charged-current muonic neutrino (antineutrino) cross section on water for the T2K neutrino (antineutrino) beam. We validate our model by comparing with the available inclusive electron scattering data on oxygen and compare our predictions with the recent T2K -O data, finding good agreement at all kinematics. We show that the results are very similar to those obtained for C scattering, except at low energies, and we comment on the origin of this difference. A factorized spectral function model of O is also included for purposes of comparison.

    Correlation between heavy flavour production and multiplicity in pp and p-Pb collisions at high energy in the multi-pomeron exchange model

    Grigory Feofilov🇷🇺 · Vladimir Kovalenko🇷🇺 · Andrei Puchkov (Saint Petersburg State University)🇷🇺

    The multiplicity dependence of heavy flavour production in pp-collisions at LHC energies is studied in the framework of the multi-pomeron exchange model. The model is introducing the string-string interaction collectivity effects in pp collisions, which modifies multiplicity and transverse momenta, leading to the non-trivial mean pt vs. multiplicity (<pt>_Nch - Nch) correlation. The string collectivity strength parameter is fixed by experimental data on multiplicity and transverse momentum correlation in a wide energy range (from ISR to LHC). The particles discrimination is implemented according to Schwinger mechanism taking into account the strong decays of hadron resonances. We demonstrate, that the faster-than-linear growth of the open charm production with the event charged particle multiplicity, observed in experimental pp high energy collisions, can be explained by the modification of the string tension due to the increasing overlap and interaction of quark-gluon strings. The model is extended for p-A interactions and the calculations for p-Pb collisions are performed.
