Double Higgs production and quadratic divergence cancellation in little Higgs models with T-parity
(2006-05-01)
We analyze double Higgs boson production at the Large Hadron Collider in the context of Little Higgs models. In double Higgs production, the diagrams involved are directly related to those that cause the cancellation of ...
The correlation matrix of Higgs rates at the LHC
(2016-11-01)
The imperfect knowledge of the Higgs boson decay rates and cross sections at the LHC constitutes a critical systematic uncertainty in the study of the Higgs boson properties. We show that the full covariance matrix between ...
Hidden sector effects on double Higgs production near threshold at the LHC
(Elsevier B.V., 2011-08-19)
In this Letter we study a novel effect of a hidden sector coupling to the standard model Higgs boson: an enhancement of the Higgs pair production cross section near threshold due to bound state effects. After summing the ...
Stratifications on the Moduli Space of Higgs Bundles
(2016-11-02)
The moduli space of Higgs bundles has two stratifications. The Bia lynickiBirula stratification comes from the action of the non-zero complex numbers by multiplication on the Higgs field, and the Shatz stratification arises ...
Higgs flavor violation as a signal to discriminate models
(Springer, 2015-11-12)
We consider the Higgs Lepton Flavor Violating process h -> tau mu, in which CMS found a 2.5 sigma excess of events, from a model independent perspective, and find that it is difficult to generate this operator without also ...
Multiple higgs and vector boson production beyond the standard model
(2013-05-17)
If the electroweak symmetry breaking is originated from a strongly coupled sector, as for instance in composite Higgs models, the Higgs boson couplings can deviate from their Standard Model values. In such cases, at ...
Dirac gaugions, R symmetry and the 125 GeV Higgs
(Springer, 2015-04-20)
We study a supersymmetric scenario with a quasi exact R-symmetry in light of the discovery of a Higgs resonance with a mass of 125 GeV. In such a framework, the additional adjoint superfields, needed to give Dirac masses ...
Probing the top-Higgs sector with composite Higgs models at present and future hadron colliders
(2021-03-01)
We study the production of tt¯ h and tt¯ hh at hadron colliders, in the minimal Composite Higgs Models, based on the coset SO(5)/SO(4). We explore the fermionic representations 5 and 14. A detailed phenomenological analysis ...
A Bayesian view of the Higgs sector with higher dimensional operators
(2013-08-15)
We investigate the possibilities of New Physics affecting the Standard Model (SM) Higgs sector. An effective Lagrangian with dimension-six operators is used to capture the effect of New Physics. We carry out a global ...
