摘要:

我们研究了在CLIC的$eγ$和$γγ$碰撞中通过$ν\barν$产生的非标准$γν\barν$和$γγν\barν$耦合。在线性对撞机的$eγ$和$γγ$对撞机模式中,考虑入射光子的后向散射光子分布函数和初态电子的初态辐射(ISR)和束致辐射(BS)效应,得到了$γν\barν$和$γγν\barν$耦合的95%置信区间.我们表明,反应$γγ\toν\barν$提供了超过15个数量级的改善中微子双光子耦合相比,LEP限制。

英文摘要:

We have examined nonstandard $γν\barν$ and $γγν\barν$ couplings via $ν\barν$ production in a $eγ$ and $γγ$ collisions at the CLIC. We obtain 95% confidence level bounds on $γν\barν$ and $γγν\barν$ couplings by considering the backscattered photon distribution function for incoming photons and Initial State Radiation (ISR) and Beamstrahlung (BS) effect for initial state electrons in the $eγ$ and $γγ$ collider modes of linear collider. We indicate that the reaction $γγ\toν\barν$ provides more than 15 orders of magnitude improvement in neutrino-two photon couplings compared to LEP limits.
