A possible resolution of the CDF $\psi$' anomaly

We consider the contribution of radially excited 2^3P_{1,2} states to psi^prime production at the Tevatron energy. Production of these states via the conventional gluon fusion mechanism and via gluon and charm quark fragmentation processes is considered. We find that it is possible to account for th...

description We consider the contribution of radially excited 2^3P_{1,2} states to psi^prime production at the Tevatron energy. Production of these states via the conventional gluon fusion mechanism and via gluon and charm quark fragmentation processes is considered. We find that it is possible to account for the data on psi^prime production from the CDF experiment, by taking into account the decays of these 2^3P_{1,2} states into psi^prime.

Production of these states via the conventional gluon fusion mechanism and via gluon and charm quark fragmentation processes is considered. We find that it is possible to account for the data on psi~prime production from the CDF experiment, by taking into account the decays of these 2~3P_{1,2} states into psi~prime.We consider the contribution of radially excited 2 3 P 1,2 states to Ψ′ production at the Tevatron energy. Production of these states via the conventional gluon fusion mechanism and via gluon and charm quark fragmentation processes is considered. With optimistic estimates of the decay branching fractions of these 2 3 P 1,2 states into Ψ′, it is possible to account for the large Ψ′ production cross-section observed by the CDF experiment.hep-ph/9409232CERN-TH-7434-94TIFR-TH-94-33CERN-TH-7434-94TIFR-TH-94-33oai:cds.cern.ch:2681481994-09-06
