Rare semileptonic decay of \(\chi_{c1}(1p)\) meson In QCD

The rare semileptonic \(\chi_{c1}(1p)\rightarrow D_{s}^{+}e\bar{\nu }\) decay is analyzed, by using the three-point QCD sum rules. Taking into account the two-gluon condensate contributions, the transition form factors related to this decay are calculated and are used to determine the total decay wi...

Summary:The rare semileptonic \(\chi_{c1}(1p)\rightarrow D_{s}^{+}e\bar{\nu }\) decay is analyzed, by using the three-point QCD sum rules. Taking into account the two-gluon condensate contributions, the transition form factors related to this decay are calculated and are used to determine the total decay width and branching fraction. Our findings may be approved by future experiments.
