In-medium properties of D_s and D_s mesons in magnetic matter - effects of spin-mixing

Heavy flavour mesons consist of one or more quark (antiquark) belonging to the heavy flavors (charm or bottom). The study of the in-medium properties (masses, decay widths etc.) of the heavy flavour hadrons is a topic of extensive research in the high energy, heavy ion collision experiments. The estimation of strong magnetic fields produced in the peripheral ultra relativistic heavy-ion collision experiments at LHC, RHIC [1] has initiated a lot of research on hadron properties in presence of magnetic fields. There is a profuse production of the open heavy flavour mesons at the early stages of the collisions, where produced magnetic field can still be large. Thus, the effects of magnetic fields on the heavy flavor mesons should have important observable consequences in such high energy collisions. The present investigation is restricted to the nuclear matter case, in presence of an external magnetic field
