Particle Physics at the European Spallation Source
H. Abele, A. Alekou, A. Algora +176
Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will be the world's brightest neutron source. As such, it has the potential for a particle physic…
Reactor neutrino oscillations as constraints on Effective Field Theory
Adam Falkowski, Martín González-Alonso, Zahra Tabrizi
We study constraints on the Standard Model Effective Field Theory (SMEFT) from neutrino oscillations in short-baseline reactor experiments. We calculate the survival probability of…
The CKM parameters in the SMEFT
Sébastien Descotes-Genon, Adam Falkowski, Marco Fedele +2
The extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix from flavour observables can be affected by physics beyond the Standard Model (SM). We provide a general roadmap to tak…
The MORA project
P. Delahaye, E. Liénard, I. Moore +25
The MORA (Matter's Origin from the RadioActivity of trapped and oriented ions) project aims at measuring with unprecedented precision the D correlation in the nuclear beta decay of…
Hadronic tau decays as New Physics probes in the LHC era
Vincenzo Cirigliano, Adam Falkowski, Martín González-Alonso +1
We analyze the sensitivity of hadronic tau decays to non-standard interactions within the model-independent framework of the Standard Model Effective Field Theory (SMEFT). Both exc…
Adding Pseudo-Observables to the Four-Lepton Experimentalist's Toolbox
James S. Gainer, Martín González-Alonso, Admir Greljo +12
The "golden" channel, in which the newly-discovered Higgs boson decays to four leptons by means of intermediate vector bosons, is important for determining the properties of the Hi…
New physics searches in nuclear and neutron decay
Martin Gonzalez-Alonso, Oscar Naviliat-Cuncic, Nathal Severijns
The status of tests of the standard electroweak model and of searches for new physics in allowed nuclear decay and neutron decay is reviewed including both theoretical and expe…
Compilation of low-energy constraints on 4-fermion operators in the SMEFT
Adam Falkowski, Martín González-Alonso, Kin Mimouni
We compile information from low-energy observables sensitive to flavor-conserving 4-fermion operators with two or four leptons. Our analysis includes data from e+e- colliders, neut…
Anomalous Triple Gauge Couplings in the Effective Field Theory Approach at the LHC
Adam Falkowski, Martin Gonzalez-Alonso, Admir Greljo +2
We discuss how to perform consistent extractions of anomalous triple gauge couplings (aTGC) from electroweak boson pair production at the LHC in the Standard Model Effective Field…
Kinematic sensitivity to the Fierz term of -decay differential spectra
Martin Gonzalez-Alonso, Oscar Naviliat-Cuncic
The current most stringent constraints on exotic scalar or tensor couplings in neutron and nuclear decay, involving left-handed neutrinos, are obtained from the Fierz interfere…

A. Rodríguez-Sánchez, M. González-Alonso, A. Pich
We analyze the lowest spectral moments of the left-right two-point correlation function, using all known short-distance constraints and the recently updated ALEPH V-A spectral func…
Global constraints on anomalous triple gauge couplings in effective field theory approach
Adam Falkowski, Martin Gonzalez-Alonso, Admir Greljo +1
We present a combined analysis of LHC Higgs data (signal strengths) together with LEP-2 WW production measurements. To characterize possible deviations from the Standard Model (SM)…
