在光子对撞机上测量希格斯玻色子的双光子衰变宽度

Towards a measurement of the two-photon decay width of the Higgs boson at a Photon Collider

Klaus Moenig, Aura Rosca

摘要:

本文研究了在光子-光子碰撞中,质量为120 GeV的希格斯玻色子的双光子衰变宽度乘以分支比的测量,假设在光谱的高能部分,γ-γ积分亮度为80 fb^-1。该分析是基于重建的希格斯事件产生的伽马伽马--> H过程,其次是希格斯衰变成一个bbbar对。在一年的数据采集中,测量双光子宽度乘以希格斯玻色子玻色子衰变为b夸克的分支比的统计误差为2.1%.

英文摘要:

A study of the measurement of the two photon decay width times the branching ratio of a Higgs boson with the mass of 120 GeV in photon - photon collisions is presented, assuming a gamma-gamma integrated luminosity of 80 fb^-1 in the high energy part of the spectrum. The analysis is based on the reconstruction of the Higgs events produced in the gamma gamma --> H process, followed by the decay of the Higgs into a bbbar pair. A statistical error of the measurement of the two-photon width times the branching ratio of the Higgs boson decaying into b-quarks is found to be 2.1% for one year of data taking.
