论文摘要
在高能量的Leptonic碰撞中,远高于Electroweak量表,通过初始状态辐射和最终状态淋浴,Electroweak仪表玻色子的共线分裂机理成为主要现象。我们指出,在将来的高能Lepton Colliders,例如多TEV MUON撞机,Electroweak Parton分布功能(EW PDF)应作为初始状态的党派碰撞的适当描述。 Leptons和Electroweak仪表玻色子是EW Partons,它根据不间断的标准模型(SM)量规组进化,并且有效地恢复了潜在的较大的共线对数。我们在近代领先的LOG(NLL)精度上为EW PDF提供了形式主义。我们为未来的多TEV MUON对撞机的某些重要SM过程计算半包含的横截面。我们得出的结论是,将EW PDF形式主义用于未来的高能量Lepton Colliders是适当的。
In high-energy leptonic collisions well above the electroweak scale, the collinear splitting mechanism of the electroweak gauge bosons becomes the dominant phenomena via the initial state radiation and the final state showering. We point out that at future high-energy lepton colliders, such as a multi-TeV muon collider, the electroweak parton distribution functions (EW PDFs) should be adopted as the proper description for partonic collisions of the initial states. The leptons and electroweak gauge bosons are the EW partons, that evolve according to the unbroken Standard Model (SM) gauge group and that effectively resum potentially large collinear logarithms. We present a formalism for the EW PDFs at the Next-to-Leading-Log (NLL) accuracy. We calculate semi-inclusive cross sections for some important SM processes at a future multi-TeV muon collider. We conclude that it is appropriate to adopt the EW PDF formalism for future high-energy lepton colliders.
