Abstract

The form factors of the semileptonicχb2(1P)→Bcl¯νdecay are calculated by using the QCD sum rule technique. The results obtained are then used to estimate the decay widths of this transition in all lepton channels. The orders of decay rates indicate that this transition is accessible at LHC for all lepton channels.

Highlights

Quarkonia are flavorless bound states composed of combinations of quarks and their antiquarks
We use the values of transition form factors to estimate the decay rate of the transition under consideration at all lepton channels
In QCD or theoretical side we evaluate it in terms of QCD degrees of freedom like quark masses as well as quark and gluon condensates via operator product expansion (OPE)

Summary

Introduction

Quarkonia are flavorless bound states composed of combinations of quarks and their antiquarks. Taking into account the two-gluon condensate corrections, the transition form factors of the semileptonic χb2(1P) → Bcl] decay channel are calculated within the three-point QCD sum rule. We use the values of transition form factors to estimate the decay rate of the transition under consideration at all lepton channels.
