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…
Weak nuclear decays deep-underground as a probe of axion dark matter
Jorge Alda, Carlo Broggini, Giuseppe Di Carlo +4
We investigate the time modulation of weak nuclear decays as a method to probe axion dark matter. To this end, we develop a theoretical framework to compute the -dependence of w…
Collider and astrophysical signatures of light scalars with enhanced couplings
Jorge Alda, Gabriele Levati, Paride Paradisi +2
Beyond Standard Model scenarios addressing the flavor puzzle and the hierarchy problem generally predict dominant new physics couplings with fermions of the third generation. In th…
Radiative Quarkonium decays into an Invisible ALP
Luca Di Luzio, Alfredo Walter Mario Guerrera, Xavier Ponce Díaz +1
In this talk the ALP production from radiative quarkonium decays is presented. To this purpose, the relevant cross-section is computed from a effective Lagrangian containing…
Axion-Like Particles in Radiative Quarkonia Decays
Luca Di Luzio, Alfredo Walter Mario Guerrera, Xavier Ponce Díaz +1
Radiative quarkonia decays offer an ideal setting for probing Axion-Like Particle (ALP) interactions. This paper provides a comprehensive review of ALP production mechanisms throug…
UV-IR interplay in axion flavour violation
Luca Di Luzio, Alfredo Walter Mario Guerrera, Xavier Ponce Díaz +1
Flavour-violating axions appear in models where the Peccei-Quinn(PQ) charges are generation non-universal. Consequently, this charge arrangement will also generate flavour violatio…
On the IR/UV flavour connection in non-universal axion models
Luca Di Luzio, Alfredo Walter Mario Guerrera, Xavier Ponce Díaz +1
Non-universal axion models, with the Peccei-Quinn (PQ) symmetry acting on Standard Model (SM) fermions in a generation-dependent way, are typically accompanied by two different sou…
ALP production in weak mesonic decays
Alfredo Walter Mario Guerrera, Stefano Rigolin
Axion-Like-Particles are among the most economical and well motivated extensions of the Standard Model. In this work ALP production from hadronic and leptonic meson decays are stud…
Leptonic Meson Decays into Invisible ALP
Jorge Alda Gallo, Alfredo Walter Mario Guerrera, Siannah Peñaranda +1
The theoretical calculation of pseudo-scalar leptonic decay widths into an invisible ALP, , is reviewed. Assuming generic flavour-conserving ALP couplings…
Revisiting decays
Alfredo Walter Mario Guerrera, Stefano Rigolin
The theoretical calculation for pseudo--scalars hadronic decays is reviewed. %with the Axion-Like-Particle escaping the detection, While one-loop penguin contributions a…
