Inclusive Jet Production in Photon-Photon Collisions at sqrt(s_ee) from 189 to 209 GeV

The OPAL collaboration

摘要:

本文研究了质心能量为189 ~ 209 GeV的LEP束辐射准实光子碰撞中的包容喷流产生(e+e-> e+e- +jet+X)。使用kp射流算法重建射流。包容性微分截面测量为射流横向动量的函数,ptjet,在5 <ptjet < 40 GeV的范围内,对于伪快速性,etaj,在-1.5 < etaj < 1.5的范围内。将结果与强耦合常数下次领先阶微扰QCD的预测进行了比较。

英文摘要:

Inclusive jet production (e+e- -> e+e- +jet+X) is studied in collisions of quasi-real photons radiated by the LEP beams at e+e- centre-of-mass energies sqrt see from 189 to 209 GeV. Jets are reconstructed using the kp jet algorithm. The inclusive differential cross-section is measured as a function of the jet transverse momentum, ptjet, in the range 5 <ptjet < 40 GeV for pseudo-rapidities, etaj, in the range -1.5 < etaj < 1.5. The results are compared to predictions of perturbative QCD in next-to-leading order in the strong coupling constant.
