Quantum numbers of the Xð3872Þ state and orbital angular momentum in its ρ0J=ψ decay
J=ψ → μþμ−, are used to measure orbital angular momentum contributions and to determine the JPC value of the Xð3872Þ meson. The data correspond to an integrated luminosity of 3.0 fb−1 of proton-proton collisions collected with the LHCb detector. This determination, for the first time performed without assuming a value for the orbital angular momentum, confirms the quantum numbers to be JPC 1⁄4 ...
متن کاملRemarks on the quantum numbers of Xð3872Þ from the invariant mass distributions of the J=c and!J=c final states
Yu. S. Kalashnikova, A. E. Kudryavtsev, and A.V. Nefediev Institute for Theoretical and Experimental Physics, 117218, B. Cheremushkinskaya 25, Moscow, Russia (Received 1 December 2011; published 6 January 2012) We reanalyze the twoand three-pion mass distributions in the decays Xð3872Þ ! J=c and Xð3872Þ ! !J=c and argue that the present data favor the 1þþ assignment for the quantum numbers of t...

متن کاملEffects of final state interaction in B^+_c to D^0 K^+ decay
In this paper, the decay of Bc+ meson, which consists of two b and c heavy quarks, into the Do and K+ mesons was studied. Given that the experimental branching ratio for this decay was within the range of 3.75*10-5 to 11.16*10-5; it was decided to calculate the theoretical branching ratio by applying the final state interaction (FSI) through the T and cross-section channels. In this process, b...

متن کاملFinal State Interaction Effects in B+→J/ψ π+ Decay
In this research the exclusive decay of is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...
