A frame independent classification of single field inflationary models
Laur Järv, Kristjan Kannike, Luca Marzola +5
Seemingly unrelated models of inflation that originate from different physical setups yield, in some cases, identical predictions for the currently constrained inflationary observa…
Ultra High Energy Cosmic Rays & Super-heavy Dark Matter
Luca Marzola, Federico R Urban
We reanalyse the prospects for upcoming Ultra-High Energy Cosmic Ray experiments in connection with the phenomenology of Super-heavy Dark Matter. We identify a set of observables w…
Radiative Yukawa Couplings in the Simplest Left-Right Symmetric Model
Emidio Gabrielli, Luca Marzola, Martti Raidal
We revisit a recent solution to the flavor hierarchy problem based on the paradigm that Yukawa couplings are, rather than fundamental constants, effective low energy couplings radi…
Heavy spin-2 Dark Matter
Eugeny Babichev, Luca Marzola, Martti Raidal +4
We provide further details on a recent proposal addressing the nature of the dark sectors in cosmology and demonstrate that all current observations related to Dark Matter can be e…
Minimal but non-minimal inflation and electroweak symmetry breaking
Luca Marzola, Antonio Racioppi
We consider the most minimal scale invariant extension of the standard model that allows for successful radiative electroweak symmetry breaking and inflation. The framework involve…
Gravitational Origin of Dark Matter
Eugeny Babichev, Luca Marzola, Martti Raidal +4
Observational evidence for the existence of Dark Matter is limited to its gravitational effects. The extensive program for dedicated searches has yielded null results so far, chall…
Polarization observables for millicharged particles in photon collisions
Emidio Gabrielli, Luca Marzola, Edoardo Milotti +1
Particles in a hidden sector can potentially acquire a small electric charge through their interaction with the Standard Model and can consequently be observed as millicharged part…
Large loop-coupling enhancement of a heavy pseudoscalar from a light dark sector
Stefano Di Chiara, Andi Hektor, Kristjan Kannike +2
The small background and the sensitivity to charged particles via a leading order loop coupling make the diphoton channel a privileged experimental test for new physics models. We…
Reconstruction of the Higgs mass in events with Higgs bosons decaying into a pair of tau leptons using matrix element techniques
L. Bianchini, B. Calpas, J. Conway +4
We present an algorithm for the reconstruction of the Higgs mass in events with Higgs bosons decaying into a pair of tau leptons. The algorithm is based on matrix element (ME) tech…
Naturalness of the relaxion mechanism
Andrew Fowlie, Csaba Balazs, Graham White +2
The relaxion mechanism is a novel solution to the hierarchy problem. In this first statistical analysis of the relaxion mechanism, we quantify the relative plausibility of a QCD an…
Di-photon excess at LHC and the gamma ray excess at the Galactic Centre
Andi Hektor, Luca Marzola
Motivated by the recent indications for a 750 GeV resonance in the di-photon final state at the LHC, in this work we analyse the compatibility of the excess with the broad photon e…
