Multi-loop Integrand Reduction via Multivariate Polynomial Division
Hans van Deurzen, Gionata Luisoni, Pierpaolo Mastrolia +4
We present recent developments on the topic of the integrand reduction of scattering amplitudes. Integrand-level methods allow to express an amplitude as a linear combination of Ma…
The NESSiE Concept for Sterile Neutrinos
L. Stanco, A. Anokhina, A. Bagulya +78
Neutrino physics is nowadays receiving more and more attention as a possible source of information for the long-standing problem of new physics beyond the Standard Model. The recen…
Multi-leg One-loop Massive Amplitudes from Integrand Reduction via Laurent Expansion
Hans van Deurzen, Gionata Luisoni, Pierpaolo Mastrolia +3
We present the application of a novel reduction technique for one-loop scattering amplitudes based on the combination of the integrand reduction and Laurent expansion. We describe…
Very boosted Higgs in gluon fusion
Christophe Grojean, Ennio Salvioni, Matthias Schlaffer +1
The Higgs production and decay rates offer a new way to probe new physics beyond the Standard Model. While dynamics aiming at alleviating the hierarchy problem generically predict…
Neutrino and Charged Lepton Flavour Today
R. Alonso, M. B. Gavela, D. Hernandez +2
Flavour physics is a priceless window on physics beyond the Standard Model. In particular, flavour violation in the lepton sector looks very promising, as high precision measuremen…
W-propagator corrections to muon and tau leptonic decays
M. Fael, L. Mercolli, M. Passera
We derive the corrections induced by the W-boson propagator to the differential rates of the leptonic decay of a polarized muon and tau lepton. Results are presented both for decay…
Disentangling a dynamical Higgs
I. Brivio, T. Corbett, O. J. P. Éboli +5
The pattern of deviations from Standard Model predictions and couplings is different for theories of new physics based on a non-linear realization of the gau…
An Equivalent Gauge and the Equivalence Theorem
Andrea Wulzer
I describe a novel covariant formulation of massive gauge theories in which the longitudinal polarization vectors do not grow with the energy. Therefore in the present formalism, d…
Light-Front Quantum Chromodynamics: A framework for the analysis of hadron physics
B. L. G. Bakker, A. Bassetto, S. J. Brodsky +17
An outstanding goal of physics is to find solutions that describe hadrons in the theory of strong interactions, Quantum Chromodynamics (QCD). For this goal, the light-front Hamilto…
GoSam applications for automated NLO calculations
G. Cullen, H. van Deurzen, N. Greiner +10
We present applications of the program GoSam for the automated calculation of one-loop amplitudes. Results for NLO QCD corrections to beyond the Standard Model processes as well as…
NNLO nucleon parton distributions from a light-cone quark model dressed with its virtual meson cloud
Marco Traini
A detailed study of nucleon parton distribution functions is performed within a radiative Next-to-Next-to Leading Order (NNLO) parton model whose low-scale input is rigidly describ…
Light Sterile Neutrinos in Cosmology and Short-Baseline Oscillation Experiments
S. Gariazzo, C. Giunti, M. Laveder
We analyze the most recent cosmological data, including Planck, taking into account the possible existence of a sterile neutrino with a mass at the eV scale indicated by short-base…
Probing top quark electromagnetic dipole moments in single-top-plus-photon production
Matteo Fael, Thomas Gehrmann
The production of a single top quark in association with an isolated photon probes the electromagnetic coupling structure of the top quark. We investigate the sensitivity of kinema…
Higgs Couplings in Composite Models
Marc Montull, Francesco Riva, Ennio Salvioni +1
We study Higgs couplings in the composite Higgs model based on the coset SO(5)/SO(4). We show that the couplings to gluons and photons are insensitive to the elementary-composite m…
Pragmatic View of Short-Baseline Neutrino Oscillations
C. Giunti, M. Laveder, Y. F. Li +1
We present the results of global analyses of short-baseline neutrino oscillation data in 3+1, 3+2 and 3+1+1 neutrino mixing schemes. We show that the data do not allow us to abando…
NLO QCD corrections to Higgs boson production plus three jets in gluon fusion
G. Cullen, H. van Deurzen, N. Greiner +6
We report on the calculation of the cross section for Higgs boson production in association with three jets via gluon fusion, at next-to-leading-order (NLO) accuracy in QCD, in the…
The Effective Theory of Self-Interacting Dark Matter
Brando Bellazzini, Mathieu Cliche, Philip Tanedo
We present an effective non-relativistic theory of self-interacting dark matter. We classify the long range interactions and discuss how they can be generated from quantum field th…

Hans van Deurzen, Gionata Luisoni, Pierpaolo Mastrolia +3
We present the calculation of the cross section for Higgs boson production in association with a top quark pair plus one jet, at next-to-leading-order (NLO) accuracy in QCD. All ma…
Multiloop Integrand Reduction for Dimensionally Regulated Amplitudes
P. Mastrolia, E. Mirabella, G. Ossola +1
We present the integrand reduction via multivariate polynomial division as a natural technique to encode the unitarity conditions of Feynman amplitudes. We derive a recursive formu…
Mixing Patterns from the Groups Sigma (n phi)
Claudia Hagedorn, Aurora Meroni, Lorenzo Vitale
We survey the mixing patterns which can be derived from the discrete groups Sigma (36 x 3), Sigma (72 x 3), Sigma (216 x 3) and Sigma (360 x 3), if these are broken to abelian subg…
