高能下$l^+l^-\to W^+W^-$中的希格斯玻色子交换效应

Higgs Boson Exchange Effects in $l^+l^-\to W^+W^-$ at High Energy

U. Baur, E. Brewer

摘要:

我们考虑了在产生一对W玻色子的高能μ ^+ μ ^-、e^+ e^-和τ ^+ τ ^-碰撞中探测希格斯交换图效应的前景。对过程l^+l^- -> W^+W^-(其中l=mu,e,tau)进行了解析和数值模拟分析,以确定质心能量sqrt{s}_H,其中希格斯交换的影响变得相关。还研究了sqrt{s}_H与入射轻子质量的标度关系。特别考虑了实验接受截断后的W^+W^- -> l^pm} nu_l_j终态。角切割被证明能够显著降低sqrt{s}_H。

英文摘要:

We consider the prospects for detecting effects due to the Higgs exchange diagram in high energy mu^+ mu^-$, e^+ e^-, and tau^+ tau^- collisions producing a pair of W bosons. The processes l^+l^- -> W^+W^- (with l=mu,e,tau) are analyzed, analytically and via numerical simulations, to determine the center of mass energy, sqrt{s}_H, where the effects from Higgs exchange become relevant. The scaling of sqrt{s}_H with the mass of the incoming leptons is also studied. Special consideration is given to the W^+W^- -> l^pm} nu_l jj final state after experimental acceptance cuts are imposed. Angular cuts are shown to be able to significantly lower sqrt{s}_H.
