| 英文摘要 | The production of j/psi mesons in jets is studied in the forward region of proton-proton collisions using data collected with the lhcb detector at a center-of-mass energy of 13 tev. the fraction of the jet transverse momentum carried by the j/psi meson, z(j/psi) p(t) (j/psi) / p(t)(jet) is measured using jets with p(t)(jet) > 20 gev in the pseudorapidity range 2.5 < eta(jet) < 4.0. the observed z(j/psi) distribution for j/psi mesons produced in b-hadron decays is consistent with expectations. however, the results for prompt j/psi production do not agree with predictions based on fixed-order nonrelativistic qcd. this is the first measurement of the p(t) fraction carried by prompt j/psi mesons in jets at any experiment. |
