我们研究了新物理对标准模型希格斯扇区的影响，重点是对希格斯自耦合的影响。我们证明了一个低质量的Higgs粒子，m（h）<2 m（t），由于在TeV的新相互作用的影响，可以有很强的有效自耦合。我们调查的可能性，这种相互作用的第一个证据可能是希格斯-希格斯束缚态。为此，我们构建了一个有效的场论形式主义来研究这样一个低质量的希格斯玻色子的物理。我们探讨了在欧洲核子研究中心的大型强子对撞机的希格斯场（Higgsium）的非相对论束缚态的可能性，并构建了一个非相对论有效场理论的希格斯部门，是适合这样的研究（NRHET）。
We examine the effects of new physics on the Higgs sector of the standard model, focusing on the effects on the Higgs self-couplings. We demonstrate that a low mass Higgs, m(h)< 2m(t), can have a strong effective self-coupling due to the effects of a new interaction at a TeV. We investigate the possibility that the first evidence of such an interaction could be a Higgs-Higgs bound state. To this end, we construct an effective field theory formalism to examine the physics of such a low mass Higgs boson. We explore the possibility of a nonrelativistic bound state of the Higgs field (Higgsium) at CERN's Large Hadron Collider and construct a nonrelativistic effective field theory of the Higgs sector that is appropriate for such studies (NRHET).
