Zero-damped modes of near-extremal Reissner--Nordström black holes from exact WKB
Prisco Lo Chiatto, Sebastian Schenk, Nils Wagner +1
The late-time ringdown dynamics of near-extremal black holes (BHs) are expected to be dominated by zero-damped modes (ZDMs), whose decay rates are parametrically suppressed relativ…
Oscillating Imprints of Dark Matter in Mesons Decays
Prisco Lo Chiatto, Babette Döbrich, Gilad Perez
We study scenarios in which ultralight dark matter (ULDM) causes oscillations of the Cabibbo--Kobayashi--Maskawa (CKM) matrix elements, considering two frameworks. The first, previ…
ECFA Higgs, electroweak, and top Factory Study
H. Abidi, J. A. Aguilar-Saavedra, S. Airen +373
The ECFA Higgs, electroweak, and top Factory Study ran between 2021 and 2025 as a broad effort across the experimental and theoretical particle physics communities, bringing togeth…
Search for hadronic decays of feebly-interacting particles at NA62
NA62 Collaboration
The NA62 experiment at CERN has the capability to collect data in a beam-dump mode, where 400 GeV protons are dumped on an absorber. In this configuration, New Physics particles, i…
Interference Resurrection of the Dipole through Quantum Tomography
Prisco Lo Chiatto
Helicity selection rules can suppress the leading contributions from dimension-6 operators in the Standard Model Effective Field Theory (SMEFT), reducing sensitivity to potential n…
