E_6激发的复合Higgs模型和重子不对称产生

E_6 inspired composite Higgs model and baryon asymmetry generation

R. Nevzorov, A. W. Thomas

摘要:

在E6激发的复合Higgs模型(E6 CHM)中,在强相互作用扇区中,SU(6)整体对称性在f > 10 TeV附近被破坏到SU(5)子群,产生了一组伪Nambu-Goldstone玻色子(pNGB),其中包括一个标准模型(SM)单重标量场、一个类SM的Higgs二重场和一个SU(3)_C三重标量场$T$。我们认为,在E6 CHM中的重子数破坏可以导致所观察到的物质-反物质不对称性,如果CP被破坏。质量在几TeV范围内的标量场的彩色三重态在这一过程中起着关键作用,并可能导致一个独特的新的物理信号,可以在不久的将来在大型强子对撞机上检测到。

英文摘要:

The breakdown of SU(6) global symmetry down to its SU(5) subgroup near the scale f > 10 TeV in the strongly interacting sector within the E_6 inspired composite Higgs model (E6CHM) gives rise to a set of pseudo-Nambu-Goldstone bosons (pNGBs) that involves one Standard Model (SM) singlet scalar, a SM-like Higgs doublet and an SU(3)_C triplet of scalar fields, $T$. We argue that the baryon number violation in the E6CHM can induce the observed matter-antimatter asymmetry if CP is violated. The coloured triplet of scalar fields with mass in the few TeV range plays a key role in this process and may lead to a distinct new physics signal that can be detected at the LHC in the near future.
