The Galactic Center Excess from Z3 Scalar Semi-Annihilations
Yi Cai, Andrew Paul Spray
We investigate the possibility of the Z3 scalar singlet model explaining the Fermi galactic centre excess. We find a good fit to the measured spectral excess in the region where th…
Implications of diphoton searches for a Radion in the Bulk-Higgs Scenario
Peter Cox, Anibal D. Medina, Tirtha Sankar Ray +1
In this work we point out that the apparent diphoton excess initially presented by the ATLAS and CMS collaborations could have originated from a radion in the bulk Higgs scenario w…
Novel Collider and Dark Matter Phenomenology of a Top-philic Z'
Peter Cox, Anibal D. Medina, Tirtha Sankar Ray +1
We consider extending the Standard Model by including an additional Abelian gauge group broken at low energies under which the right-handed top quark is the only effectively charge…
Semi-Annihilating Wino-Like Dark Matter
Andrew P. Spray, Yi Cai
Semi-annihilation is a generic feature of dark matter theories with symmetries larger than Z_2. We explore a model based on a Z_4-symmetric dark sector comprised of a scalar single…
Long-Lived, Colour-Triplet Scalars from Unnaturalness
James Barnard, Peter Cox, Tony Gherghetta +1
Long-lived, colour-triplet scalars are a generic prediction of unnatural, or split, composite Higgs models where the spontaneous global-symmetry breaking scale TeV a…
Fermionic Semi-Annihilating Dark Matter
Yi Cai, Andrew Paul Spray
Semi-annihilation is a generic feature of dark matter theories with symmetries larger than Z2. We investigate two examples with multi-component dark sectors comprised of an SU(2)L…
