The LHCb Collaboration has reported for the first time the branching fraction for the decay as . They measured the branching fraction of this decay relative to that of the normalization channel as . In this work, we have studied the and decays in three scales of μ and strong coupling values mesons using a simple model based on the framework of the factorization approach presented. We have obtained for decay at and for decay at . We have also estimated at which is consistent with the experimental result.
期刊介绍:
General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology.
Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate).
EPL also publishes Comments on Letters previously published in the Journal.
