Photoproduction of H C
Using the NRQCD factorization formalism, we calculate the total cross section for the photoproduction of hc mesons. We include color-octet and color-singlet mechanisms as well as next-to-leading order perturbative QCD corrections. The theoretical prediction depends on two nonperturbative matrix elements that are not well determined from existing data on charmonium production. For reasonable val...
متن کاملSubthreshold photoproduction of charm
Charm photoproduction rates off nuclei below the nucleon threshold are estimated using the phenomenologically known structure functions both for x < 1 and x > 1. The rates rapidly fall below the threshold from values ∼10 pb for Pb close to the threshold (at 7.5 GeV) to ∼1pb at 6 GeV.

متن کاملPhotoproduction of neutral pions
The pion and nucleon mass differences generate a very pronounced cusp in the photoproduction reaction of a single neutral pion on the proton. A nonrelativistic effective field theory to describe this reaction is constructed. The approach is rigorous in the sense that it is an effective field theory with a consistent power counting scheme. Expressions for the Sand P-wave multipole amplitudes at ...
متن کاملState Photoproduction
It is shown that the list of unusual mesons planned for a careful study in photoproduction can be extended by the exotic states X(1600) with I(J) = 2(2) which should be looked for in the ρρ decay channels in the reactions γN → ρρN and γN → ρρ∆. The full classification of the ρρ states by their quantum numbers is presented. A simple model for the spin structure of the γp → f2(1270)p, γp → a2(132...
