Top-quark effects in diphoton production through gluon fusion at NLO in QCD
Fabio Maltoni, Manoj K. Mandal, Xiaoran Zhao
At hadron colliders, the leading production mechanism for a pair of photons is from quark-anti-quark annihilation at the tree level. However, due to large gluon-gluon luminosity, t…
Atomki Anomaly in Family-Dependent Extension of the Standard Model
Luigi Delle Rose, Shaaban Khalil, Simon J. D. King +2
In the context of a gauge invariant, non-anomalous and family-dependent (non-universal) extension of the Standard Model, wherein a new high scale mechanism generates masses…
New Physics Suggested by Atomki Anomaly
Luigi Delle Rose, Shaaban Khalil, Simon J. D. King +1
We consider several extensions of the Standard Model (SM) which can explain the anomalies observed by the Atomki collaboration in the decay of excited states of Beryllium via a new…
Low-scale leptogenesis assisted by a real scalar singlet
Tommi Alanne, Thomas Hugle, Moritz Platscher +1
Standard thermal leptogenesis in the type-I seesaw model requires very heavy right-handed neutrinos (RHNs). This makes it hard to probe this scenario experimentally and results in…
Evaluating multi-loop Feynman integrals numerically through differential equations
Manoj K. Mandal, Xiaoran Zhao
The computation of Feynman integrals is often the bottleneck of multi-loop calculations. We propose and implement a new method to efficiently evaluate such integrals in the physica…
Planck mass and inflation as consequences of dynamically broken scale invariance
Jisuke Kubo, Manfred Lindner, Kai Schmitz +1
Classical scale invariance represents a promising framework for model building beyond the Standard Model. However, once coupled to gravity, any scale-invariant microscopic model re…
Like-sign dileptons with mirror type composite neutrinos at the HL-LHC
Matteo Presilla, Roberto Leonardi, Orlando Panella
Within a mirror type assignment for the excited composite fermions the neutrino mass term is built up from a Dirac mass, , which gives the mass of charged lepton component of…
Seeking leptoquarks in the plus missing energy channel at the high-luminosity LHC
Natascia Vignaroli
The plus missing energy channel is one of the most efficient to detect third-generation leptoquarks (LQs). It offers an important test to models which explain flavor anom…
Closing the window on single leptoquark solutions to the -physics anomalies
Andrei Angelescu, Damir Bečirević, Darius A. Faroughy +1
We examine various scenarios in which the Standard Model is extended by a light leptoquark state to solve for one or both -physics anomalies, viz. $R_{D^{(\ast)}}^\mathrm{exp}>…
Hot Axions and the tension
Francesco D'Eramo, Ricardo Z. Ferreira, Alessio Notari +1
Scattering and decay processes of thermal bath particles involving heavy leptons can dump hot axions in the primordial plasma around the QCD phase transition. We compute their reli…
Constraints on Spin-Dependent Dark Matter Scattering with Long-Lived Mediators from TeV Observations of the Sun with HAWC
A. Albert, R. Alfaro, C. Alvarez +91
We analyze the Sun as a source for the indirect detection of dark matter through a search for gamma rays from the solar disk. Capture of dark matter by elastic interactions with th…
Molière Scattering in Quark-Gluon Plasma: Finding Point-Like Scatterers in a Liquid
Francesco D'Eramo, Krishna Rajagopal, Yi Yin
By finding rare (but not exponentially rare) large-angle deflections of partons within a jet produced in a heavy ion collision, or of such a jet itself, experimentalists can find t…
The strange side of LHCb
Martino Borsato, Vladimir Gligorov, Diego Guadagnoli +2
We provide general effective-theory arguments relating present-day discrepancies in semi-leptonic -meson decays to signals in kaon physics, in particular lepton-flavour violatin…
Testable Axion-Like Particles In The Minimal Linear σ Model
Javier Alonso-Gonzalez, Luca Merlo, Federico Pobbe +2
Axion and axion-like particle models are typically affected by a strong fine-tuning problem in conceiving the electroweak and the Peccei-Quinn breaking scales. Within the context o…
A gauged horizontal symmetry and
Diego Guadagnoli, Méril Reboud, Olcyr Sumensari
One of the greatest challenges for models of anomalies is the necessity to produce a large contribution to a quark times a lepton current, , and to avo…
Learning New Physics from a Machine
Raffaele Tito D'Agnolo, Andrea Wulzer
We propose using neural networks to detect data departures from a given reference model, with no prior bias on the nature of the new physics responsible for the discrepancy. The vi…
Implications of scalar and tensor explanations of
Ferruccio Feruglio, Paride Paradisi, Olcyr Sumensari
We investigate the implications of scalar and tensor operators proposed to accommodate the hints of lepton flavor universality violation in charged-current -meson decays. We sho…
Master integrals for the NNLO virtual corrections to scattering in QED: the non-planar graphs
Stefano Di Vita, Stefano Laporta, Pierpaolo Mastrolia +2
We evaluate the master integrals for the two-loop non-planar box-diagrams contributing to the elastic scattering of muons and electrons at next-to-next-to-leading order in QED. We…
Scalar leptoquarks from GUT to accommodate the -physics anomalies
Damir Bečirević, Ilja Doršner, Svjetlana Fajfer +3
We address the -physics anomalies within a two scalar leptoquark model. The low-energy flavor structure of our set-up originates from two operators that relate Yukawa co…
Sub-GeV Dark Matter Shining at Future MeV Gamma-Ray Telescopes
Francesco D'Eramo, Stefano Profumo
We propose a novel framework where light (sub-GeV) dark matter (DM) is detectable with future MeV gamma-ray telescopes without conflicting with Cosmic Microwave Background (CMB) da…
Low-energy Effects of Lepton Flavour Universality Violation
Claudia Cornella, Ferruccio Feruglio, Paride Paradisi
The persisting anomalous data in semileptonic B-decays point towards New Physics models exhibiting large sources of Lepton Flavour Universality Violation. In this work we generalis…
Seeking leptoquarks in IceCube
Damir Bečirević, Boris Panes, Olcyr Sumensari +1
We investigate the sensitivity of IceCube(-Gen2) to a scalar leptoquark scenario with couplings only to heavy quark flavors which may be connected to solving discrepancies in -m…
Current and future constraints on Higgs couplings in the nonlinear Effective Theory
Jorge de Blas, Otto Eberhardt, Claudius Krause
We perform a Bayesian statistical analysis of the constraints on the nonlinear Effective Theory given by the Higgs electroweak chiral Lagrangian. We obtain bounds on the effective…
Model-Independent Short-Baseline Oscillations from Reactor Spectral Ratios
S. Gariazzo, C. Giunti, M. Laveder +1
We consider the ratio of the spectra measured in the DANSS neutrino experiment at 12.7 and 10.7~m from a nuclear reactor. These data give a new model-independent indication in favo…
