The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Building blocks of the flavourful SMEFT RG
Camila S. Machado, Sophie Renner, Dave Sutherland
A powerful aspect of effective field theories is connecting scales through renormalisation group (RG) flow. The anomalous dimension matrix of the Standard Model Effective Field The…
New Physics Searches at Kaon and Hyperon Factories
Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka +61
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths…
Flavor probes of axion-like particles
Martin Bauer, Matthias Neubert, Sophie Renner +2
Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-energy extensions of the Standard Model (SM). We investigate the phenomenology of an ALP with fl…
ALP-SMEFT Interference
Anne Mareike Galda, Matthias Neubert, Sophie Renner
The Standard Model Effective Field Theory (SMEFT) offers a powerful theoretical framework for parameterizing the low-energy effects of heavy new particles with masses far above the…
Consistent treatment of axions in the weak chiral Lagrangian
Martin Bauer, Matthias Neubert, Sophie Renner +2
We present a consistent implementation of weak decays involving an axion or axion-like particle in the context of an effective chiral Lagrangian. We argue that previous treatments…
The Low-Energy Effective Theory of Axions and ALPs
Martin Bauer, Matthias Neubert, Sophie Renner +2
Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-energy extensions of the Standard Model, which interact with the known particles through higher-…
The impact of flavour data on global fits of the MFV SMEFT
Rafael Aoude, Tobias Hurth, Sophie Renner +1
We investigate the information that can be gained by including flavour data in fits of the Standard Model Effective Field Theory (SMEFT) with the assumption of Minimal Flavour Viol…
Computing Tools for the SMEFT
Editors, :, Jason Aebischer +22
The increasing interest in the phenomenology of the Standard Model Effective Field Theory (SMEFT), has led to the development of a wide spectrum of public codes which implement aut…
Axion-like particles, lepton-flavor violation and a new explanation of and
Martin Bauer, Matthias Neubert, Sophie Renner +2
Axion-like particles (ALPs) with lepton-flavor violating couplings can be probed in exotic muon and tau decays. The sensitivity of different experiments depends strongly on the ALP…
Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider
Juliette Alimena, James Beacham, Martino Borsato +198
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Had…
Matching for FCNC effects in the flavour-symmetric SMEFT
Tobias Hurth, Sophie Renner, William Shepherd
We calculate the complete tree and one-loop matching of the dimension 6 Standard Model Effective Field Theory (SMEFT) with unbroken flavour symmetry to the operators of th…
Maximal Flavour Violation: a Cabibbo mechanism for leptoquarks
Luca Di Luzio, Javier Fuentes-Martin, Admir Greljo +2
We propose a mechanism that allows for sizeable flavour violation in quark-lepton currents, while suppressing flavour changing neutral currents in quark-quark and lepton-lepton sec…
A flavoured dark sector
Sophie Renner, Pedro Schwaller
We explore the phenomenology of a QCD-like dark sector which confines around the GeV scale. The dark sector inherits a flavour structure from a coupling between dark quarks and SM…
Exploring Peaks and Valleys in the Diphoton Spectrum
Nathaniel Craig, Sophie Renner, Dave Sutherland
We investigate the effects of resonance-continuum interference on the diphoton spectrum in the presence of a new spin-0 or spin-2 state produced via gluons or quarks and decaying t…
Di-photon Excess Explained by a Resonant Sneutrino in R-parity Violating Supersymmetry
B. C. Allanach, P. S. Bhupal Dev, S. A. Renner +1
We explain the recent excess seen by ATLAS and CMS experiments at around 750 GeV in the di-photon invariant mass as a narrow width sneutrino decaying to di-photons via a stau loop…
Linear flavour violation and anomalies in B physics
Ben Gripaios, M. Nardecchia, S. A. Renner
We propose renormalizable models of new physics that can explain various anomalies observed in decays of B-mesons to electron and muon pairs. The new physics states couple to linea…
Composite leptoquarks and anomalies in -meson decays
Ben Gripaios, Marco Nardecchia, S. A. Renner
We attempt to explain recent anomalies in semileptonic decays at LHCb via a composite Higgs model, in which both the Higgs and an -triplet leptoquark arise as pseudo-G…
Hint of Lepton Flavour Non-Universality in Meson Decays
Diptimoy Ghosh, Marco Nardecchia, S. A. Renner
The LHCb collaboration has recently presented their result on R_K = BR(B+ -> K+ mu+ mu-)/ BR(B+ -> K+ e+ e-) for the dilepton invariant mass bin m_{ll}^2 = 1-6 GeV^2 (l = mu, e). T…
Large Hadron Collider constraints on a light baryon number violating sbottom coupling to a top and a light quark
B. C. Allanach, S. A. Renner
We investigate a model of R-parity violating (RPV) supersymmetry in which the right-handed sbottom is the lightest supersymmetric particle, and a baryon number violating coupling i…
