量子临界希格斯粒子:从AdS $_5$到对撞机

Quantum Critical Higgs: From AdS$_5$ to Colliders

Ali Shayegan Shirazi, John Terning

摘要:

我们研究量子临界希格斯模型在大型强子对撞机和未来更高的能量对撞机独特的签名。在这些模型中,希格斯玻色子是一个共形扇区的一部分,在阈值尺度上被柔和地打破,一般来说,希格斯玻色子的标度维度比标准模型中的大。特别地,我们检查了$gg\to H \to ZZ$、$gg\to H\to γγ$和$gg\to Z\to HZ$通道,以查看在高不变质量区域中横截面如何偏离标准模型。为了进行计算,我们使用5D量子临界希格斯模型使用AdS/CFT对应,用软壁打破共形对称。

英文摘要:

We examine distinctive signatures of Quantum Critical Higgs models at the LHC and future higher energy colliders. In these models the Higgs boson is part of a conformal sector that is softly broken at a threshold scale, and generically the scaling dimension of the Higgs is larger than in the Standard Model. In particular we examine the $gg\to H \to ZZ$, $gg\to H\to γγ$, and $gg\to Z\to HZ$ channels to see how the cross sections deviate from the Standard Model in the high invariant mass region. In order to perform the calculations we use 5D duals of Quantum Critical Higgs models using the AdS/CFT correspondence, with a soft wall to break the conformal symmetry.
