To this purpose, we … Web10 de fev. de 2014 · The couplings of the SM-like Higgs with matter fermions and gauge bosons generally contain the parameters α and β, where β represents the ratio of the VEVs, tanβ ≡ vu / vd. The decoupling limit of the MSSM is achieved by sending the SUSY breaking mass scale MSUSY to infinity.

Web17 de fev. de 2016 · We show that in addition to these features the model insures the positivity of the Higgs quartic coupling through its interactions to the dark matter multiplet and 126. We also show that the Higgs mass squared runs negative triggering electroweak symmetry breaking. WebWe present a simple mechanism for generating a Higgs quartic in composite Higgs models without a corresponding quadratic term. The extra quartic will originate from a Higgs … Web13 de abr. de 2024 · Measuring the Higgs boson cubic and quartic couplings, or getting equivalently information on the exact shape of the Higgs potential, is therefore an … how many maverick movies are there
