To measure the characteristics of quark and gluon jets in hadron-hadron collisions, two samples of jets are used. Given the large statistics of jets at the LHC, the two-sample method requires taking into account the following corrections: (1) use of measured fractions of quark and gluon jets instead of the model ones, (2) amendment for the contribution of jets with an unidentified flavour, (3) taking into account the dependence of the distributions of quark and gluon jets on the conditions for jet sample selections. The paper presents an improved two-sample method that takes into account these corrections. |
