ALP-Mediated Dark Matter at Low Reheating Temperature and the Belle II Excess
Joel Jones-Pérez, Luca Merlo, Javier Silva-Malpartida
Belle II has reported a excess in over its Standard Model prediction, recently interpreted as arising from an axion-like particle mediating a thermal dark…
Mass Generation for Axion Like Particles
Luca Merlo
The most widely accepted solution to the Strong CP problem is the QCD axion, whose traditional parameter space is relatively constrained. However, recent studies on exotic axion mo…
How to Identify a Majoron: Effective Field Theories of Spontaneous Lepton Number Breaking
Carla Biggio, Marta Fuentes Zamoro, Xu Li +2
We revisit the traditional type~I, II, and III seesaw mechanisms in the presence of a complex scalar field charged under a global symmetry that can be identified with lepton…
Crossing into the Region for Leptophilic ALPs
Marta F. Zamoro, Álvaro Lozano-Onrubia, Luca Merlo +1
Axion-like particles (ALPs) are typically identified as pseudoscalars whose couplings are shift-symmetry invariant with the exception of their couplings to gauge bosons and their m…
WISPedia -- the WISPs Encyclopedia
Conrado Albertus, Francesca Chadha-Day, Arturo de Giorgi +8
The Weakly-Interacting Slim Particle encyclopedia (WISPedia) is a comprehensive reference work dedicated to the systematic compilation of theoretical models, Effective Field Theori…
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…
ALPaca: The ALP Automatic Computing Algorithm
Jorge Alda, Marta Fuentes Zamoro, Luca Merlo +2
The ALP Automatic Computing Algorithm, ALPaca, is an open source Python library devoted to studying the phenomenology of Axion-Like Particles (ALPs) with masses in the ranges $m_a…
Comprehensive ALP Searches in Meson Decays
Jorge Alda, Marta Fuentes Zamoro, Luca Merlo +2
We present a comprehensive study of axion-like particles (ALPs) in meson decays, combining effective field theory and ultraviolet models within the open-source tool ALPaca. The ana…
GeV ALP from TeV Vector-like leptons
Arturo de Giorgi, Marta Fuentes Zamoro, Luca Merlo
We present a model where a GeV axion-like-particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei-Quinn symmetry-breaking terms…
ALPs and HNLs at LHC and Muon Colliders: Uncovering New Couplings and Signals
Marta Burgos Marcos, Arturo de Giorgi, Luca Merlo +1
Axion-like particles (ALPs) and heavy neutral leptons (HNLs) are two well-motivated classes of particles beyond the Standard Model. It is intriguing to explore the new detection op…

Arturo de Giorgi, Marta Fuentes Zamoro, Luca Merlo
We present a model where a GeV axion-like-particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei-Quinn symmetry-breaking terms…
