LHC的Mueller Navelet射流-完成NLL BFKL计算

Mueller Navelet jets at LHC - complete NLL BFKL calculation

D. Colferai, F. Schwennsen, L. Szymanowski, S. Wallon

摘要:

我们计算了LHC中Mueller Navelet喷流的截面和方位角解扰,在完整的次领先阶BFKL框架下,即包括对Green函数的次领先修正和对Mueller Navelet顶点的次领先修正。对Mueller Navelet喷流研究中提出的标准观测量所得到的结果表明,这两种修正源对观测量的最终量级和最终行为具有同等的重要性。令人惊讶的结论是,我们的分析是,在本文件的完整的次领先阶BFKL框架内获得的观测值是非常相似的次领先对数DGKL型处理内获得的相同的观测值。这一事实使人们对LHC对Mueller Navelet喷流的研究将导致BFKL和DGKL动力学之间的明确区分的普遍看法产生了怀疑。

英文摘要:

We calculate cross section and azimuthal decorrellation of Mueller Navelet jets at the LHC in the complete next-lo-leading order BFKL framework, i.e. including next-to-leading corrections to the Green's function as well as next-to-leading corrections to the Mueller Navelet vertices. The obtained results for standard observables proposed for studies of Mueller Navelet jets show that both sources of corrections are of equal, big importance for final magnitude and final behavior of observables. The astonishing conclusion of our analysis is that the observables obtained within the complete next-lo-leading order BFKL framework of the present paper are quite similar to the same observables obtained within next-to-leading logarithm DGLAP type treatment. This fact sheds doubts on general belief that the studies of Mueller Navelet jets at the LHC will lead to clear discrimination between the BFKL and the DGLAP dynamics.
