在LHC上用轻子味违反Slepton衰变来测试I型和II跷跷板

Lepton flavour violating slepton decays to test type-I and II seesaw at the LHC

Albert Villanova del Moral

摘要:

在LHC上对Slepton衰变中的轻子味破坏(LFV)进行观测,可以间接检验I型和II型跷跷板机制。在普适味盲边界条件下,中微子区的LFV与slepton区的LFV通过重整化群方程联系起来。LFV斯莱普顿衰变率的比率结果是一个非常有效的方法来提取留下的中微子部门的印记。研究了I型跷跷板机制中的一些中微子情形。此外,对于I型和II型跷跷板机制,在最小超重力参数空间进行扫描,以估计LFV slepton衰减率可以有多大,同时尊重当前的低能量约束。

英文摘要:

Searches at the LHC of lepton flavour violation (LFV) in slepton decays can indirectly test both type-I and II seesaw mechanisms. Assuming universal flavour-blind boundary conditions, LFV in the neutrino sector is related to LFV in the slepton sector by means of the renormalization group equations. Ratios of LFV slepton decay rates result to be a very effective way to extract the imprint left by the neutrino sector. Some neutrino scenarios within the type-I seesaw mechanism are studied. Moreover, for both type-I and II seesaw mechanisms, a scan over the minimal supergravity parameter space is performed to estimate how large LFV slepton decay rates can be, while respecting current low-energy constraints.
