Higgs chaotic inflation in standard model and NMSSM

Standard Model Higgs boson mass from inflation

We analyse one-loop radiative corrections to the inflationary potential in the theory, where inflation is driven by the Standard Model Higgs field. We show that inflation is possible provided the Higgs mass mH lies in the interval mmin < mH < mmax, where mmin = [136.7 + (mt − 171.2) × 1.95] GeV, mmax = [184.5 + (mt − 171.2) × 0.5] GeV and mt is the mass of the top quark. Moreover, the predictio...

Standard Model Higgs boson mass from inflation: two loop analysis

We extend the analysis of [1] of the Standard Model Higgs inflation accounting for two-loop radiative corrections to the effective potential. As was expected, higher loop effects result in some modification of the interval for allowed Higgs masses mmin < mH < mmax, which somewhat exceeds the region in which the Standard Model can be considered as a viable effective field theory all the way up t...

CP-odd Higgs in NMSSM

We study the sensitivity of rare decay π → e+e− to the light CP-odd Higgs A01 in the NMSSM. It is shown that the 3.3σ discrepancy between theoretical prediction and the recent KTeV measurement of B(π0 → e+e−) can be resolved with two narrow bands of NMSSM parameter space. For mA0 1 = 214.3 MeV, i.e., A01 as the state in Σ + → pμ+μ− decay found by HyperCP Collaboration, π → e+e− constrains |Xd| ...

Higgs Masses and Couplings in the Nmssm

We give the upper bounds on the masses of the lightest and second lightest CP even Higgs bosons in the NMSSM, the MSSM extended by a gauge singlet. The dominant two loop corrections are included. Since the coupling R of the lightest Higgs scalar to gauge bosons can be small, we study in detail the relation between masses and couplings of both lightest scalars. We present upper bounds on the mas...
