- W4380684658 abstract "We investigate the in-medium masses of the pseudoscalar $(D,overline{D},{D}_{s}^{ifmmodepmelsetextpmfi{}})$, and vector $({D}^{*},{overline{D}}^{*},{D}_{s}^{*ifmmodepmelsetextpmfi{}})$, open charm mesons in isospin asymmetric magnetized nuclear matter, accounting for the effects of the Dirac sea. The masses are used to study the in-medium partial decay widths of ${D}^{*}ensuremath{rightarrow}Densuremath{pi}$ (${overline{D}}^{*}ensuremath{rightarrow}overline{D}ensuremath{pi}$) and $mathrm{ensuremath{Psi}}(3770)ensuremath{rightarrow}Doverline{D}$, using the $^{3}P_{0}$ model. The in-medium masses of the open charm mesons are calculated from their interactions with the nucleons and scalar mesons within the generalized chiral effective model in terms of the scalar and number densities of nucleons and the scalar fields fluctuations. The free energy of the magnetized vacuum with Landau energy levels and anomalous magnetic moments (AMMs) of the charged fermions in the single fermion energies are taken into account in the Dirac sea contribution. The effects of Landau energy levels of protons and AMMs of the nucleons are also considered in the magnetized nuclear matter. The light quark condensates are modified considerably with magnetic field, leading to (inverse) magnetic catalysis due to the magnetized Dirac sea effects. The magnetic field causes modifications to occur due to the mixing of the pseudoscalar and longitudinal component of the vector mesons, along with the lowest Landau-level contribution to the ground-state energy of the charged mesons as point-particle correction. For the charmonium state $mathrm{ensuremath{Psi}}(3770)$, the effects of the magnetized Dirac sea are incorporated to the mass modifications through the medium-modified scalar dilaton field $ensuremath{chi}$ within the chiral model. The in-medium masses and decay widths of the open charm and charmonium mesons thus obtained should have important observable consequences in the production of the open charm mesons and charmonia in noncentral ultrarelativistic heavy-ion collision experiments, where huge magnetic fields are expected to be created." @default.
