味对称多标量模型的新Higgs信号

New Higgs signals from a multi-scalar model with flavor symmetry

Alfredo Aranda, J. Lorenzo Diaz-Cruz, Alfonso Rosado

摘要:

一个场景中的$s$,$c$,和$b$夸克融合希格斯生产截面的标准模型的增强。特别是$c$夸克聚变的产生是非常重要的,可以解释在大型强子对撞机的重大贡献。轻希格斯耦合矢量玻色子被充分抑制,使其质量低于115 GeV的LEP约束,由于增强耦合到第二家族费米子,希格斯衰变到$μ$对是足够大的,可以检测到。这是一个模型,将三个希格斯粒子的双重下的味道对称收费。

英文摘要:

A scenario is presented where the $s$, $c$, and $b$ quark fusion Higgs production cross sections are enhanced with respect to those of the Standard Model. In particular the $c$ quark fusion production is very important and can account for a significant contribution at the Large Hadron Collider. The light Higgs couplings to vector bosons are sufficiently suppressed to allow its mass to lie below the LEP bound of 115 GeV and due to enhanced couplings to second family fermions, the Higgs decay to $μ$ pairs is large enough to be detectable. This is accomplished with a model incorporating three Higgs doublets charged under a flavor symmetry.
