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…
Dark matter and spin-1 milli-charged particles
Emidio Gabrielli, Luca Marzola, Martti Raidal +1
New physics scenarios beyond the Standard Model predict the existence of milli-charged particles. So far, only spin-1/2 and spin-0 milli-charged particles have been considered in l…
Muon g-2 and galactic centre -ray excess in a scalar extension of the 2HDM type-X
Andi Hektor, Kristjan Kannike, Luca Marzola
We consider an extension of the lepto-specific 2HDM with an extra singlet as a dark matter candidate. Taking into account theoretical and experimental constraints, we investiga…
