Firstly, it admits a sizable radiative contribution to the Higgs boson mass m , up to ~4 GeV in the case of an IR-fixed point of the coupling Y LH 谓 and a large sneutrino mixing. Secondly, the lightest sneutrino, highly complex as expected, is a viable thermal DM candidate. Owing ...

Here, we introduce the gauge-boson mass\(M_Z\), the electroweak mixing angle\(\theta _W\), the quark masses\(m_q\), as well as\(\beta \), which is defined via the ratio of the Higgs vacuum expectation values of the MSSM,\(\tan \beta \equiv v_u/v_d\). The charge and th...
As a consequence of this new formulation we are able to present an answer to the question: what is the origin of the mass of the Higgs boson?doi:10.1103/PhysRevD.86.063510M. NovelloE. BittencourtPhysical review D: Particles and fields...

The triviality and vacuum stability bounds on the Higgs-boson mass (m) are reexamined in the presence of weakly coupled new interactions parametrized in a model-independent way by effective operators of dimension 6. The constraints from precision tests of the standard model are taken into account...
The Higgs boson mass, the fine structure constant, the Weinberg angle, the critical exponents are estimated by polymer statistics methods. Friction forces have electroweak nature. New phase transitions by changing the even number of components of an ordering field, n, near the α - relaxation tran...
