通过左右对称在LHC处的跷跷板

Seesaw at LHC through Left - Right Symmetry

Goran Senjanovic

摘要:

我认为,LHC可以揭示中微子质量的本质,通过探索的跷跷板机制。确凿的证据是通过产生相同符号的轻子对而产生的轻子数违反,这是一种对撞机模拟的无中微子双β衰变。我在L-R对称理论的背景下讨论这一点,这导致了最初的中微子质量和跷跷板机制。质量在几TeV范围内的W_R规范玻色子可以很容易地支配无中微子双β衰变,它在LHC上的发现将具有宇称恢复和轻子数破坏的壮观特征。此外,LHC可以测量右手中微子的质量和右手轻子混合矩阵,这反过来又可以用来预测无中微子双衰变和轻子味违反违反过程的速率。LHC能量下的LR尺度为在目前和即将到来的实验中观察这些低能过程提供了很大的希望。

英文摘要:

I argue that LHC may shed light on the nature of neutrino mass through the probe of the seesaw mechanism. The smoking gun signature is lepton number violation through the production of same sign lepton pairs, a collider analogy of the neutrinoless double beta decay. I discuss this in the context of L-R symmetric theories, which led originally to neutrino mass and the seesaw mechanism. A W_R gauge boson with a mass in a few TeV region could easily dominate neutrinoless double beta decay, and its discovery at LHC would have spectacular signatures of parity restoration and lepton number violation. Moreover, LHC can measure the masses of the right-handed neutrinos and the right-handed leptonic mixing matrix, which could in turn be used to predict the rates for neutrinoless double decay and lepton flavor violating violating processes. The LR scale at the LHC energies offers great hope of observing these low energy processes in the present and upcoming experiments.
