Pavel Fileviez Perez, Tao Han, Sogee Spinner, Maike K. Trenkel

摘要:

研究了在大型强子对撞机(LHC)上寻找色跷跷板方案中轻子数破坏信号的可能性。在这种情况下,在单圈水平上产生中微子质量的场是SU(3)的标量和马约拉纳费米子色八隅体。由于QCD的强相互作用,这些态可以在LHC中以有利的速率产生。研究了同号双轻子通道中轻子数破坏信号的产生机制和衰变过程。在最简单的情况下,当两个费米子色八隅体在质量上是简并的,人们可以用它们的衰变来区分中微子光谱。我们发现,对于质量高达约1 TeV的费米子八隅体的同号双轻子事件的数量是大于标准模型的背景表明一个有前途的信号,为新的物理。

英文摘要:

The possibility to search for lepton number violating signals at the Large Hadron Collider (LHC) in the colored seesaw scenario is investigated. In this context the fields that generate neutrino masses at the one-loop level are scalar and Majorana fermionic color-octets of SU(3). Due to the QCD strong interaction these states may be produced at the LHC with a favorable rate. We study the production mechanisms and decays relevant to search for lepton number violation signals in the channels with same-sign dileptons. In the simplest case when the two fermionic color-octets are degenerate in mass, one could use their decays to distinguish between the neutrino spectra. We find that for fermionic octets with mass up to about 1 TeV the number of same-sign dilepton events is larger than the standard model background indicating a promising signal for new physics.
