A SUSY Inspired Simplified Model for the 750 GeV Diphoton Excess
E. Gabrielli, K. Kannike, B. Mele +3
The evidence for a new singlet scalar particle from the 750 GeV diphoton excess, and the absence of any other signal of new physics at the LHC so far, suggest the existence of new…
Non-minimal CW inflation, electroweak symmetry breaking and the 750 GeV anomaly
Luca Marzola, Antonio Racioppi, Martti Raidal +2
We study whether the hinted 750 GeV resonance at the LHC can be a Coleman-Weinberg inflaton which is non-minimally coupled to gravity. Since the inflaton must couple to new charged…
First interpretation of the 750 GeV di-photon resonance at the LHC
Stefano Di Chiara, Luca Marzola, Martti Raidal
We scrutinise the evidences recently reported by the ATLAS and CMS collaborations for compatible 750 GeV resonances which appear in the di-photon channels of the two experiments in…
Natural Relaxation
Luca Marzola, Martti Raidal
Motivated by natural inflation, we propose a relaxation mechanism consistent with inflationary cosmology that explains the hierarchy between the electroweak scale and Planck scale.…
Relaxion Cosmology and the Price of Fine-Tuning
Stefano Di Chiara, Kristjan Kannike, Luca Marzola +3
The relaxion scenario presents an intriguing extension of the standard model in which the particle introduced to solve to the strong CP problem, the axion, also achieves the dynami…
Linear inflation from quartic potential
Kristjan Kannike, Antonio Racioppi, Martti Raidal
We show that if the inflaton has a non-minimal coupling to gravity and the Planck scale is dynamically generated, the results of Coleman-Weinberg inflation are confined in between…
