Abstract

The breakdown of \(SU(6)\) global symmetry down to its \(SU(5)\) subgroup near the scale \(f \geqslant 10\) 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.

E 6启发的复合希格斯模型和重子不对称生成

摘要

在（（{{E} _ ）内的强相互作用扇区中，\（SU（6）\）全局对称性分解到其尺度（\ f \ geqslant 10 \）附近的\（SU（5）\）子组。{6}} \）启发的复合希格斯模型（E ₆ CHM）产生了一组伪纳姆布-戈德斯通玻色子（pNGB），其中涉及一个标准模型（SM）单重态标量，一个类似SM的希格斯双重态和一个\ （SU {{（3）} _ {C}} \）标量字段的三元组\（T \）。我们认为E ₆中的重子数违反如果违反CP，CHM可能会引起观察到的物质-反物质不对称性。质量在几个TeV范围内的标量场的彩色三重态在此过程中起关键作用，并可能导致可以在不久的将来在LHC上检测到的独特的新物理信号。
