Open strange mesons in (magnetized) nuclear matter

We investigate the mass modifications of open strange mesons (vector K* and axial vector K1) in isospin asymmetric nuclear matter using quantum chromodynamics sum rule (QCDSR) approach. The in-medium decay widths of K* -> K pi and K1 -> K*pi are studied from the mass modifications of K1, K* and K mesons, using a light quark-antiquark pair creation model, namely the 3P0 model. The in-medium decay width for K1 -> K*pi is compared with the decay widths calculated using a phenomenological Lagrangian. The effects of magnetic fields are also studied on mass and partial decay width of vector K* meson decaying to K pi.
