Higgs三重态模型中希格斯玻色子玻色子耦合的辐射修正

Radiative corrections to the Higgs boson couplings in the Higgs triplet model

Mariko Kikuchi

摘要:

我们在单圈水平上计算了Higgs三重态模型(HTM)中的Higgs耦合常数,并与未来的对撞机实验进行了比较。计算了类标准模型希格斯玻色子($h$)衰变为双光子的速率.重整化Higgs与弱规范玻色子$hVV$($V=W$ \ and\ $Z$)的耦合以及三线性耦合$hhh$也在单圈水平上用壳层方案进行了计算. HTM中的$pp\rightarrow h \rightarrow γγ$通道与SM中的通道的事件率可以覆盖来自最近的LHC数据的值。我们发现,在当前数据允许的参数范围内,单循环校正的$hVV$和$hhh$顶点的偏差可以分别约为-1%和+50%。这些偏差的幅度可以足够显著,以与国际直线对撞机的精确未来数据进行比较。

英文摘要:

We calculate Higgs coupling constants at one-loop level in the Higgs triplet model (HTM) to compare to future collider experiments. We evaluate the decay rate of the standard model (SM)-like Higgs boson ($h$) into diphoton. Renormalized Higgs couplings with the weak gauge bosons $hVV$ ($V=W$\ and\ $Z$) and the trilinear coupling $hhh$ are also calculated at the one-loop level in the on-shell scheme. The event rate of the $pp\rightarrow h \rightarrow γγ$ channel in the HTM to the one in the SM can cover the value from the recent LHC data. We find that in the allowed parameter region by the current data, deviations in the one-loop corrected $hVV$ and $hhh$ vertices can be about -1% and +50%, respectively. Magnitudes of these deviations can be enough significant to compare with the precision future data at the International Linear Collider.
