在LHC上测试右手电流

Testing Right-Handed Currents at the LHC

Matti Heikinheimo, Martti Raidal, Christian Spethmann

摘要:

CMS协作组已经发布了两个不同的新物理搜索,其中包含$eejj$和$eνjj$最终状态中可能存在过量的提示。将这些暗示解释为质量为2-2.5 TeV的右手规范玻色子$W_R$的可能信号,可能对我们理解自然界和大统一的规范结构、大型强子对撞机可获得的标量扇区、中微子物理和宇宙的重子不对称性具有深远的意义。我们表明,这种解释是,事实上,符合所有现有的限制。然而,在做出过早的声明之前,我们建议在LHC 14进行一些交叉检查,以确认或伪造这种情况。其中包括对$Z_R$共振和6-7~TeV附近相关新标量扇区的搜索。此外,在单顶生产中顶夸克自旋不对称性的大影响是可能的。

英文摘要:

The CMS Collaboration has published two different searches for new physics that contain possible hints for excesses in $eejj$ and $eνjj$ final states. Interpreting those hints as a possible signal of a right-handed gauge boson $W_R$ with mass 2-2.5~TeV may have profound implications for our understanding of the gauge structure of nature and Grand Unification, the scalar sector accessible at the LHC, neutrino physics, and the baryon asymmetry of the Universe. We show that this interpretation is, indeed, consistent with all existing constraints. However, before making premature claims we propose a number of cross-checks at the LHC14 that could confirm or falsify this scenario. Those include searches for a $Z_R$ resonance and the related new scalar sector around 6-7~TeV. Additionally, large effects in top-quark spin-asymmetries in single top production are possible.
