Abstract

We report the first measurement of the Q2 distribution of X(3915) produced by single-tag two-photon interactions. The decay mode used is X(3915)→J/ψω. The covered Q2 region is from 1.5 (GeV/c)2 to 10.0 (GeV/c)2. We observe 7.9±3.1(stat)±1.5(syst) events, where we expect 4.1±0.7 events based on the Q2=0 result from the no-tag two-photon process, extrapolated to higher Q2 region using the cc¯ model of Schuler, Berends, and van Gulik. The shape of the distribution is also consistent with this model; we note that statistical uncertainties are large.

The covered Q2 region is from 1.5 (GeV/c)2 to 10.0 (GeV/c)2. We observe 7.9±3.1(stat)±1.5(syst) events, where we expect 4.1±0.7 events based on the Q2=0 result from the no-tag two-photon process, extrapolated to higher Q2 region using the cc¯ model of Schuler, Berends, and van Gulik. The shape of the distribution is also consistent with this model; we note that statistical uncertainties are large.
