Pionic dispersion relations in the presence of a weak magnetic field

In this work, dispersion relations of

Ground state energy of spin polarized quark matter with correlation

\pi^0

Effects of the Dirac sea on pion propagation in asymmetric nuclear matter

and

P-w mixing and spin dependent charge-symmetry violating potential

\pi^{\pm}

Pion Mass Modification in Presence of External Magnetic Field

have been studied in vacuum in the limit of weak external magnetic field using a phenomenological pion-nucleon

pi-eta mixing and charge symmetry violating NN potential in matter

(\pi N)

Matter-induced charge-symmetry-violating NN potential

Lagrangian. For our purpose, we have calculated the results up to one loop order in self energy diagrams with the pseudoscalar

{rho}-{omega} mixing and spin dependent charge-symmetry violating potential
