Title: 轻子味破坏衰变 L->l gamma gamma 作为研究破缺R宇称的超对称的新探针

Abstract: Lepton-flavor-violating decays of the type L->l gamma gamma (mu->e gamma gamma, tau->e gamma gamma, and tau->mu gamma gamma) are proposed as new probes of R-parity-violating supersymmetry. Non-penguin diagrams with a sneutrino that decays into two photons via a triangle graph might trigger such decays even in the absence of the corresponding radiative decays into one photon only, e.g. mu->e gamma. Thus, processes of the type L->l gamma gamma may provide an independent probe of new flavor physics. Show Chinese abstract

Abstract: 轻子味违反衰变，如L->l gamma gamma（mu->e gamma gamma，tau->e gamma gamma，和tau->mu gamma gamma）被提出作为研究破坏R宇称的超对称的新探针。 没有对应单光子辐射衰变的情况下，例如mu->e gamma，通过三角图衰变为两个光子的反中微子非雨燕图可能会引发此类衰变。 因此，类型为L->l gamma gamma的过程可能提供一种独立的新味物理探针。
