The KSVZ Atlas: A Unified SMEFT-ALP Framework
Ajdin PalavriÄ, Xavier Ponce DÃaz, Hector Tiblom
We develop a general framework for matching KSVZ-like ultraviolet completions featuring vector-like fermions and a spontaneously broken symmetry onto…
The Majoron Cosmological Window: Dark Matter and Thermal Leptogenesis
Arturo de Giorgi, Daniel Naredo-Tuero, Xavier Ponce DÃaz
The majoron is the Nambu-Goldstone boson associated with the spontaneous breaking of a global symmetry. Remarkably, the minimal majoron framework can simultaneously address t…
Insights on the Cosmic Origin of Matter from Proton Stability
Admir Greljo, Xavier Ponce DÃaz, Anders Eller Thomsen
We investigate the phenomenology of a model in which the proton is rendered absolutely stable by an IR mechanism that remains robust against unknown quantum gravity effects. A line…
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…
