Anatomy of Higgs decays into $\gamma \gamma$ and $\gamma Z$ within the EChL in the $R_\xi$ gauges [PDF]
, 2020 In this work we study the Higgs boson decays into two photons and into one photon and one $Z$ gauge boson within the context of the non-linear Effective Field Theory called the Electroweak Chiral Lagrangian.

On the GBS Bernstein-Stancu’s type operators [PDF]
Creative Mathematics and Informatics, 2013 In the present paper we establish the form of remainder term associated to the GBS (Generalized Boolean Sum) Bernstein-Stancu’s type operators, using bivariate divided differences.

The approximation of bivariate Chlodowsky-Szász-Kantorovich-Charlier-type operators
Journal of Inequalities and Applications, 2017 In this paper, we introduce a bivariate Kantorovich variant of combination of Szász and Chlodowsky operators based on Charlier polynomials. Then, we study local approximation properties for these operators.

Higgs physics beyond the SM: the non-linear EFT approach [PDF]
, 2015 Depending on whether electroweak physics beyond the Standard Model is based on a linear or on a non-linear implementation of the electroweak symmetry breaking, a linear or a chiral Effective Lagrangian is more appropriate.

On certain GBS-Durrmeyer operators based on $q$-integers
TURKISH JOURNAL OF MATHEMATICS, 2017 Summary: In the present paper we introduce the GBS (Generalized Boolean Sum) operators of Durrmeyer type based on \(q\)-integers and the approximation of B-continuous functions using the above operators is studied. In addition, a uniform convergence theorem is established and the degree of approximation in terms of mixed modulus of continuity is ...

Lepton-number violation and right-handed neutrinos in Higgs-less effective theories
, 2006 Following previous work, we identify a symmetry S_nat that generalizes the concept of custodial symmetry, keeping under control deviations from the Standard Model (SM). To realize S_nat linearly, the space of gauge fields has to be extended.
