在LHC上产生Mueller-Navelet双射流的高能再结晶效应

High-energy resummation effects in the production of Mueller-Navelet dijet at the LHC

B. Ducloué, L. Szymanowski, S. Wallon

摘要:

我们研究了Mueller和Navelet提出的在强子对撞机上产生两个具有大快度间隔的前向喷流的可能性,这是对QCD高能动力学的一种可能的检验。我们表明,使用Brodsky-Lepage-Mackenzie程序来固定重整化尺度导致最近CMS数据在大型强子对撞机的喷流的方位角相关性的一个非常好的描述。我们表明,列入下一个领先的顺序修正射流顶点显着降低的重要性,能量动量不守恒,这是固有的BFKL方法,为非对称的射流配置。最后,我们认为,在实际CMS测量的运动学中,双重部分子散射的贡献是可以忽略的。

英文摘要:

We study the production of two forward jets with a large interval of rapidity at hadron colliders, which was proposed by Mueller and Navelet as a possible test of the high energy dynamics of QCD, within a complete next-to-leading logarithm framework. We show that using the Brodsky-Lepage-Mackenzie procedure to fix the renormalization scale leads to a very good description of the recent CMS data at the LHC for the azimuthal correlations of the jets. We show that the inclusion of next-to-leading order corrections to the jet vertex significantly reduces the importance of energy-momentum non-conservation which is inherent to the BFKL approach, for an asymmetric jet configuration. Finally, we argue that the double parton scattering contribution is negligible in the kinematics of actual CMS measurements.
