Inflation and supersymmetry breaking in Higgs-R2 supergravity

A bstract We propose a new construction of the supergravity inflation as an UV completion Higgs- R 2 inflation. In dual description -supergravity, we show that there appear chiral superfields containing scalaron or sigma field in Starobinsky inflation, which unitarizes supersymmetric Higgs with large non-minimal coupling up to Planck scale. find successful slow-roll is achievable Higgs-sigma space, but under condition higher curvature terms are introduced cure tachyonic mass problems for spectator singlet scalar fields. also discuss supersymmetry breaking and its transmission visible sector result couplings gravity
