| 英文摘要 | The production of jets in association with z bosons, reconstructed via the mu(+)mu(-) and e(+)e(-) decay channels, is studied in pp and, for the first time, in pb-pb collisions. both data samples were collected by the cms experiment at the lhc, at a nucleon-nucleon center-of-mass energy of 5.02 tev. the pb-pb collisions were analyzed in the 0%-30% centrality range. the back-to-back azimuthal alignment was studied in both pp and pb-pb collisions for z bosons with transverse momentum p(t)(z) > 60 gev/c and a recoiling jet with p(t)(jet) > 30 gev/c. the p(t) imbalance x(jz) = p(t)(jet)/p(t)(z), as well as the average number of jet partners per z, r-jz, was studied in intervals of p(t)(z). the r-jz is found to be smaller in pb-pb than in pp collisions, which suggests that in pb-pb collisions a larger fraction of partons associated with the z bosons fall below the 30 gev/c p(t)(jet) threshold because they lose energy. |
