The recently announced Higgs boson discovery marks the dawn of direct probing electroweak symmetry breaking sector. Sorting out dynamics responsible for now requires interactions and searching additional states connected to this In work, we analyze constraints on couplings standard model gauge bosons using available data from Tevatron LHC.

Complete sets gauge-Higgs are considered, implementing...
In the presence of nonstandard neutrino interactions (NSI), oscillation data are affected by a degeneracy which allows solar mixing angle to be in second octant (also known as dark side) and implies sign flip atmospheric mass-squared difference. This leads an ambiguity determination ordering masses, one main goals current future experimental program. We show that recent observation coherent neutrino-nucleus scattering COHERENT experiment, combination with global data, excludes NSI at...
