Parallel Session Talk

Rare kaon decays are among the most sensitive probes of both heavy and light new physics beyond the Standard Model description thanks to high precision of the Standard Model predictions, availability of very large datasets, and the relatively simple decay topologies. The NA62 experiment at CERN is a multi-purpose high-intensity kaon decay experiment, and carries out a broad rare-decay and...

81. A Strangeness Adventure: Kaonic Atom Measurements with SIDDHARTA-2 at the DAΦNE Collider

Parallel Session Talk

In particle physics, understanding the low-energy strong interaction remains a significant challenge, demanding new experimental data as input and validation. Among the promising approaches, X-ray spectroscopy of kaonic atoms offers a unique window into the antikaon-nucleon interaction at threshold. The SIDDHARTA experiment’s measurement of kaonic hydrogen has enhanced our understanding of the...

20. The n2EDM experiment, a high-sensitivity search for the neutron electric dipole moment

Parallel Session Talk

The quest for new CP violation is a thriving field of experimental particle physics. A wide variety of experiments investigate many different particle species and processes looking for possible sources of CP violation in addition to the Standard Model. The search for a permanent neutron electric dipole moment is considered to be an excellent candidate for a possible discovery.

83. Anomaly awareness estimation in $b\to s\ell^+\ell^-$ with VAEs

Parallel track

Parallel Session Talk

Traditional statistical methods often rely on closed likelihood functional forms, which can be problematic when dealing with non-Gaussian distributions and small associated errors. This talk will address these issues by introducing Machine Learning techniques, particularly Variational Autoencoders (VAEs), to perform likelihood-free analyses. By using VAEs, we can estimate the p-value for...

7. The electron-EDM in the decoupling limit of the aligned 2HDM

Juan Manuel Dávila Illán (Universitat de València - IFIC)

Parallel track

Parallel Session Talk

We discuss model-independent contributions to the electron-EDM, focusing on those contributions emerging from a heavy scalar sector. More specifically, we investigate the aligned 2HDM in the decoupling limit. We point out that logarithmically enhanced contributions generated by Barr-Zee diagrams with a fermion loop are present in the aligned 2HDM, an effect encoded by the mixing of effective...
