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…
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…
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…
Dynamically Induced Planck Scale and Inflation
Kristjan Kannike, Gert Hütsi, Liberato Pizza +4
Theories where the Planck scale is dynamically generated from dimensionless interactions provide predictive inflationary potentials and super-Planckian field variations. We first s…
