Exploring color-octet scalar parameter space in minimal R-symmetric models

Abstract In this work we study the collider phenomenology of color-octet scalars (sgluons) in 71409543214 minimal supersymmetric models endowed with a global continuous R symmetry.We systematically catalog the significant decay channels of scalar and pseudoscalar sgluons and identify novel features that are natural in these models.These include decays in nonstandard diboson channels, such as to a gluon and a photon; three-body decays with considerable branching fractions; and long-lived particles with displaced vertex signatures.We also discuss the single and pair production m02n3ll/a of these particles and show that they can evade existing constraints from the Large Hadron Collider, to varying extents, in large regions of reasonable parameter space.

We find, for instance, that a 725 GeV scalar and a 350 GeV or lighter pseudoscalar can still be accommodated in realistic scenarios.
