Chiral shifts in heavy-light mesons

Abstract

The mass shifts of the $P$-wave $D_s$ and $B_s$ mesons due to coupling to $DK$ and $BK$ channels are calculated in the coupling channel model without fitting parameters. The strong mass shifts down for $0^{+}$ and ${1^{+}}^{\prime }$ states have been obtained, while $1^{+}"$ and $2^{+}$ states remain almost in situ. The masses of $0^{+}$ and ${1^{+}}^{\prime }$ states of $B_s$ mesons have been predicted.
