重-轻介子的手征位移

Chiral shifts in heavy-light mesons

A. M. Badalian, Yu. A. Simonov, M. A. Trusov

摘要:

在没有拟合参数的耦合沟道模型中,计算了$P$波$D_s$和$B_s$介子与$DK$和$BK$沟道耦合产生的质量位移.结果表明,$0^+$和${1^+}'$态的质量有很强的下移,而${1^+}"$和$2^+$态几乎保持原位.我们预言了$B_s$介子的$0^+$和${1^+}'$态的质量。

英文摘要:

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 ${1^+}'$ states have been obtained, while ${1^+}"$ and $2^+$ states remain almost in situ. The masses of $0^+$ and ${1^+}'$ states of $B_s$ mesons have been predicted.
