Investigating non-minimal flavour-violating CMSSM in the light of Higgs-Boson mass using information theory

Abstract

Flavour-violating interactions of the stop-quarks are expected to provide an additional few GeV contributions to the Higgs-Boson mass, particularly when mix with scharm-quarks, thereby allowing reduced supersymmetry (SUSY) breaking scale compared to flavour-conserving constrained minimal supersymmetric Standard Model (CMSSM). Inspired by this, we analyse the interactions mentioned above in the context of CMSSM using the information entropy of the Higgs-Boson for a wider region of flavour-violating CMSSM parameter space (m0,m1/2,A0, tan⁡β,sgn(μ),δctij), where δctij represents the flavour-violating coupling of the top-quark with the charm-quark and i,j defining left and right chiralities of squarks. Our information-theoretic analysis of the model mentioned above reveals the most favourable values of (m0,m1/2,A0,tan⁡β,δctij) as (4.30TeV,2.32TeV,−4.96TeV, 22.8,0.037) and (4.16TeV, 3.89TeV,−4.10TeV,19.4,0.039) for (i,j)=(L,R) and (R,L), respectively, corresponding to the maximum entropy which suggest the SUSY breaking scale to be about 5 TeV, thereby allowing considerable low values of sparticles masses than the flavour-conserving CMSSM.
