三位一体化的低能唯象:一个有效的左右对称模型

Low-energy phenomenology of trinification: an effective left-right-symmetric model

Jamil Hetzel, Berthold Stech

摘要:

三位一体化模型是基于规范群$SU(3)_C\times SU(3)_L\times SU(3)_R$的标准模型的一个有趣的扩展。我们通过构造低能有效场论来研究它的低能唯象,从而减少了需要研究的粒子数和自由参数。由此产生的模型预测,几个新的标量粒子的质量在$\mathcal{O}\left(100\text{ GeV}\right)$范围内。我们研究了一些有趣的现象学的情况下,如存在的光的费米标量除了SM-样的希格斯,或在126 GeV的退化(双)希格斯态。我们指出区域的参数空间,导致可测量的偏差从SM预测的希格斯耦合。因此,三位一体化模型将在未来几年内在大型强子对撞机上进行关键性的测试。

英文摘要:

The trinification model is an interesting extension of the Standard Model (SM) based on the gauge group $SU(3)_C\times SU(3)_L\times SU(3)_R$. We study its low-energy phenomenology by constructing a low-energy effective field theory, thereby reducing the number of particles and free parameters that need to be studied. The resulting model predicts that several new scalar particles have masses in the $\mathcal{O}\left(100\text{ GeV}\right)$ range. We study a few of the interesting phenomenological scenarios, such as the presence of a light fermiophobic scalar in addition to a SM-like Higgs, or a degenerate (twin) Higgs state at 126 GeV. We point out regions of the parameter space that lead to measurable deviations from SM predictions of the Higgs couplings. Hence the trinification model awaits crucial tests at the Large Hadron Collider in the coming years.
