Classically Scale Invariant Inflation and (A)gravity

Arsham Farzinnia

In this talk, I present the minimal classically scale-invariant and -symmetric extension of the standard model, containing one additional complex gauge singlet and three flavor…

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…

Using sorted invariant mass variables to evade combinatorial ambiguities in cascade decays

Doojin Kim, Konstantin T. Matchev, Myeonghun Park

The classic method for mass determination in a SUSY-like cascade decay chain relies on measurements of the kinematic endpoints in the invariant mass distributions of suitable colle…

Minimal Models for Axion and Neutrino

Y. H. Ahn, Eung Jin Chun

The PQ mechanism resolving the strong CP problem and the seesaw mechanism explaining the smallness of neutrino masses may be related in a way that the PQ symmetry breaking scale an…

Diphoton channel at the LHC experiments to find a hint for a new heavy gauge boson

Kunio Kaneta, Subeom Kang, Hye-Sung Lee

Recently there has been a huge interest in the diphoton excess around 750 GeV reported by both ATLAS and CMS collaborations, although the newest analysis with more statistics does…

LHC 750 GeV Diphoton excess in a radiative seesaw model

Shinya Kanemura, Kenji Nishiwaki, Hiroshi Okada +3

We investigate a possibility for explaining the recently announced 750\,GeV diphoton excess by the ATLAS and the CMS experiments at the CERN LHC in a model with multiple doubly cha…
