We calculate the transport coefficient of hadronic matter in the presence of
temperature and magnetic field using the linear sigma model. In the relaxation
time approximation, we estimate the shear viscosity over entropy density
η/s. The point-like interaction rates of hadrons are evaluated through the
S-matrix approach in the presence of a magnetic field to obtain the
temperature and magnetic field-dependent relaxation time. We observe that the
transport coefficients are anisotropic in the presence of the magnetic field.
We calculate the temperature and magnetic field-dependent anisotropic shear
viscosity coefficients by incorporating the estimated relaxation time. The
value of viscosity over entropy density is lower in the presence of a magnetic
field than the value of it in a thermal medium. The behavior of the
perpendicular components of the shear viscosity coefficient is also discussed.
We consider the temperature-dependent hadron masses from mean-field effects in
this work.Comment: 20 pages, 3 figure
