CDF Wj j过剩的R宇称破坏超对称解释

R parity violating supersymmetric explanation for the CDF Wjj excess

Dilip Kumar Ghosh, Manas Maity, Sourov Roy

摘要:

最近,CDF报告了Wjj事件样本中7.3 fb^{-1}数据中120-160 GeV之间的双喷射不变量质量分布存在4.1 sigma超额,这引起了人们的极大兴趣。我们在MSSM的一般框架下,通过τ中微子衰变到LSP stau_1和W玻色子的共振产生R宇称破坏,对这一观察提供了一个可能的解释。我们也给出了在7 TeV质心能量下运行的LHC的这种情况的预测。

英文摘要:

Recently CDF has reported a 4.1 sigma excess in the distribution of the dijet invariant mass between 120-160 GeV in Wjj event sample in 7.3 fb^{-1} of data, which has generated considerable interest. We offer a possible explanation of this observation in the general framework of MSSM with R-parity violation through resonance production of tau sneutrino decaying into the LSP stau_1 and W boson. We also give the predictions of this scenario for the LHC operating at 7 TeV center of mass energy.
