论文摘要
我们提出了PP碰撞中Diboson Productions的不对称性，作为一种新的实验性观察，可以提供有关质子结构的独特信息。提升不对称的升高是随着两个玻色子的运动学的差异，它们分别与两个不同的夸克和古怪的初始状态耦合，从而反映了夸克和反夸克的密度的不同特征。通过比较两个玻色子的运动学，例如玻色子的能量或速度，可以将其具有比夸克更高能量的Diboson事件与夸克具有更高能量的人的能量高于Antiquark。这将在某些特殊的Parton动量分数区域提供独特的信息，这无法通过大型强子对撞机或其他深层非弹性散射体验的当前W和Z测量直接证明。
We propose the boost asymmetry of the diboson productions in pp collisions as a new experimental observable, which can provide unique information on the proton structure. The boost asymmetry rises as the difference in the kinematics of the two bosons, that are coupled to the two different quark and antiquark initial states, respectively, and thus reflects different features of the quark and antiquark parton densities. By comparing the kinematics of the two bosons, such as the boson energy or rapidity, the diboson events with antiquark having higher energy than quark can be distinguished from those with quark having higher energy than antiquark. This would provide unique information in some special parton momentum fraction regions, which cannot be directly proved by current W and Z measurements at the Large Hadron Collider or other deep inelastic scattering experients.
