Effective approach to lepton observables: the seesaw case

Rupert Coy, Michele Frigerio

In the absence of direct evidence of new physics, any ultraviolet theory can be reduced to its specific set of low-energy effective operators. As a case study, we derive the effect…

LHC-friendly minimal freeze-in models

G. Bélanger, N. Desai, A. Goudelis +8

We propose simple freeze-in models where the observed dark matter abundance is explained via the decay of an electrically charged and/or coloured parent particle into Feebly Intera…

Extended Gauge Mediation in the NMSSM with Displaced LHC Signals

Marcin Badziak, Nishita Desai, Cyril Hugonie +1

We analyze models of extended Gauge Mediation in the context of the NMSSM, concentrating on supersymmetric spectra with light gluinos, low fine-tuning and decays of the lightest ne…

Probing Scalar and Pseudoscalar Solutions of the g-2 Anomaly

Fayez Abu-Ajamieh

I investigate a class of models with scalar and pseudoscalar solutions to the g-2 anomaly in the mass range between 1 MeV and 40 GeV. In particular, I investigate the constraints f…

Selecting mu -> e Conversion Targets to distinguish Lepton Flavour-Changing Operators

Sacha Davidson, Yoshitaka Kuno, Masato Yamanaka

The experimental sensitivity to conversion on nuclei is set to improve by four orders of magnitude in coming years. However, various operator coefficients add coherently i…

Majorana Neutrino Masses in the RGEs for Lepton Flavour Violation

Sacha Davidson, Martin Gorbahn, Matthew Leak

We suppose that the observed neutrino masses can be parametrised by a lepton number violating dimension-five operator, and calculate the mixing of double insertions of this operato…

The higgsino-singlino sector of the NMSSM: Combined constraints from dark matter and the LHC

Ulrich Ellwanger, Cyril Hugonie

A light singlino is a promising candidate for dark matter, and a light higgsino is natural in the parameter space of the NMSSM. We study the combined constraints on this scenario r…

Constraints on 2l2q operators from flavour-changing meson decays

Sacha Davidson, Albert Saporta

We study lepton flavour violating two- and three-body decays of pseudoscalar mesons in Effective Field Theory (EFT). We give analytic formulae for the decay rates in the presence o…

The Bearable Compositeness of Leptons

Michele Frigerio, Marco Nardecchia, Javi Serra +1

Partial compositeness as a theory of flavor in the lepton sector is assessed. We begin presenting the first systematic analysis of neutrino mass generation in this context, and ide…

Next-to-minimal dark matter at the LHC

Aoife Bharucha, Felix Brümmer, Nishita Desai

We examine the collider signatures of a WIMP dark matter scenario comprising a singlet fermion and an SU(2) n-plet fermion, with a focus on n=3 and n=5. The singlet and n-plet mass…
