Abstract

In this article, we calculate the mass shift and decay constant of isospin averaged pseudoscalar (D+D^+,D0D^0) and scalar (D0+D^+_0,D00D^0_0) mesons by the magnetic field induced quark and gluon condensates at finite density and temperature of asymmetric nuclear matter. We have calculated the in-medium chiral condensates from the chiral SU(3) mean field model and subsequently used these condensates in QCD Sum Rules (QCDSR) to calculate the effective mass and decay constant of DD mesons. Consideration of external magnetic field effects in hot and dense nuclear matter lead to appreciable modification in the masses and decay constants of DD mesons. Furthermore, we also studied the effective decay width of higher charmonium states (ψ(3686),ψ(3770),χc0(3414),χc2(3556)\psi(3686),\psi(3770),{{\chi_c}_0}(3414),{{\chi_c}_2}(3556)) as a by-product by using 3P0^3P_0 model which can have an important impact on the yield of J/ψJ/\psi mesons. The results of present work will be helpful to understand the experimental observables of the heavy ion colliders which aim to produce matter at finite density and moderate temperature.
