Study on B s → D sJ (2317,2460)l ν ¯ Semileptonic Decays in the CQM Model
Abstract
Assuming
D
∗
sJ
(2317)
and
D
sJ
(2460)
to be the

chiral partners of regular
D
s
(1968)
and
D
∗
s
(2112)
, we calculate the semileptonic decays of
B
s
to
D

,
D

(2112)
,
D

sJ
(2317)
,
D
sJ
(2460)
in terms of the Constituent Quark Meson (CQM) model. The large branching ratios of the semileptonic decays of
B
s
to
D
∗
sJ
(2317)
and
D
sJ
(2460)
indicate that those two semileptonic decays should be seen in future experiments.
