Higgs boson decay into two photons in an electromagnetic background
N. K. Nielsen
The amplitude for Higgs boson decay into two photons in a homogeneous and time-independent magnetic field is investigated by proper-time regularization in a gauge invariant manner…
Constraints on Gauge Field Production during Inflation
Sami Nurmi, Martin S. Sloth
In order to gain new insights into the gauge field couplings in the early universe, we consider the constraints on gauge field production during inflation imposed by requiring that…
LUX Constraints on Magnetic Dark Matter in the y Model with(out) Naturality
Mads T. Frandsen, Francesco Sannino, Ian M. Shoemaker +1
We study phenomenological constraints in a simple y extension of the Standard Model (SM) with a 125 GeV Higgs, a vector-like heavy electron , a complex scalar elec…
Predictions for LHC from SO(4) MWT
Ari Hietanen, Claudio Pica, Francesco Sannino +1
We investigate the vector, axial and pseudo scalar mass spectrum of an SO(4) - MWT gauge theory with fermions in the vector representation of SO(4). Here we present the preliminary…
Conformal Extensions of the Standard Model with Veltman Conditions
Oleg Antipin, Matin Mojaza, Francesco Sannino
Using the renormalisation group framework we classify different extensions of the standard model according to their degree of naturality. A new relevant class of perturbative model…
Higher Loop Corrections to the Infrared Evolution of Fermionic Gauge Theories in the RI' Scheme
Thomas A. Ryttov
We study the evolution of the gauge coupling and the anomalous dimension of the mass towards an infrared fixed point for non-supersymmetric gauge theories in the modified regulariz…
Constraints on Majorana Dark Matter from a Fourth Lepton Family
Tuomas Hapola, Matti Jarvinen, Chris Kouvaris +2
We study the possibility of dark matter in the form of heavy neutrinos from a fourth lepton family with helicity suppressed couplings such that dark matter is produced thermally vi…
On the Veltman Condition, the Hierarchy Problem and High-Scale Supersymmetry
Isabella Masina, Mariano Quiros
In this paper we have considered the possibility that the Standard Model, and its minimal extension with the addition of singlets, merges with a high-scale supersymmetric theory at…
Tools for model-independent bounds in direct dark matter searches
Eugenio Del Nobile, Marco Cirelli, Paolo Panci
We discuss a framework (based on non-relativistic operators) and a self-contained set of numerical tools to derive the bounds from some current direct detection experiments on virt…
G-structures and Flavouring non-Abelian T-duality
Alejandro Barranco, Jerome Gaillard, Niall Macpherson +2
We examine non-Abelian T-duality on backgrounds preserving N=1 supersymmetry. We show how backgrounds with SU(3)-structure are mapped to backgrounds with SU(2)-structure. We provid…
Inflationary Magnetogenesis without the Strong Coupling Problem
Ricardo J. Z. Ferreira, Rajeev Kumar Jain, Martin S. Sloth
The simplest gauge invariant models of inflationary magnetogenesis are known to suffer from the problems of either large backreaction or strong coupling, which make it difficult to…
Hints of a Charge Asymmetry in the Electron and Positron Cosmic-Ray Excesses
Isabella Masina, Francesco Sannino
By combining the recent data from AMS-02 with those from Fermi-LAT, we show the emergence of a charge asymmetry in the electron and positron cosmic-ray excesses, slightly favoring…
The universal Higgs fit
Pier Paolo Giardino, Kristjan Kannike, Isabella Masina +2
We perform a state-of-the-art global fit to all Higgs data. We synthesise them into a 'universal' form, which allows to easily test any desired model. We apply the proposed methodo…
Wormholes and Time-Machines in Nonminimally Coupled Matter-Curvature Theories of Gravity
Orfeu Bertolami, Ricardo Zambujal Ferreira
In this work we show the existence of traversable wormhole and time-machine solutions in a modified theory of gravity where matter and curvature are nonminimally coupled. Those sol…
