Query: Open bottom mesons in asymmetric nuclear matter in presence of strong
  magnetic fields   The modifications of the masses of the $B$ and $\bar B$ mesons in asymmetric
nuclear matter in the presence of strong magnetic fields, are investigated
using a chiral effective model. The medium modifications of these open bottom
mesons arise due to their interactions with the scalar mesons and the nucleons.
In the magnetized nuclear matter, the proton has contributions from the Landau
levels. In the chiral effective model, the masses of the $B$ and $\bar B$ are
calculated from the leading term, namely the vectorial Weinberg Tomozawa term
as well as from the next to leading order contributions, i.e., due to the
scalar exchange and the range terms. Due to the Weinberg-Tomozawa term, the
$\bar B$ mesons experience an attractive interaction in the symmetric nuclear
matter, whereas the $B$ mesons have a repulsive interaction. Inclusion of the
contributions from the scalar exchange and the range terms as well, leads to
drop of the masses of both $B$ and $\bar B$ mesons. The effect of the isospin
asymmetry breaks the mass degeneracy of the $B^+$ and $B^0$ (as well as of the
$B^-$ and $\bar {B^0}$) mesons, and its effect is observed to be large at high
densities. The effects of anomalous magnetic moments of the nucleons are taken
into account in the present study of the masses of the open bottom mesons in
magnetized nuclear matter.
