Quantum electrodynamics (QED) is the best understood quantum field theory. High-precision tests are being performed using free particles (e.g., the electron anomalous magnetic moment [1]). Many bound electron systems are being studied and compared to the most advanced calculations. One can cite hydrogen, positronium, muonium, highly charged, few electron ions[2] and exotic atoms (atoms in...
Kaonic atoms represent a unique laboratory for the study of the antikaon-nucleus interaction at threshold and investigate the low-energy quantum chromodynamics (QCD) in the strangeness sector. State-of-the-art X-ray detectors and modern experimental techniques allow to perform high-precision X-ray kaonic atoms spectroscopy, leading to fundamental input for nuclear, particle, and astrophysics...
The nuclear E2 resonance effect occurs when atomic de-excitation energy is closely matched by nuclear excitation energy. It produces an attenuation of some of the atomic x-ray lines from resonant versus normal isotope target. The investigation of the nuclear E2 resonance effect in kaonic ticklish atoms could provide important information about strong kaon nucleus interaction. In the past, only...
We show a novel ML and differentiable programming calibration technique and the gains it yields on the energy response of the Silicon Drift Detectors used in the VIP-2 underground experiment. This technique shows an improvement of 10 eV on the previous state-of-the-art in the VIP collaboration, in terms of Full Width at Half Maximum at 8 keV. The SDD energy resolution is a key observable in...
Pauli's Exclusion Principle (PEP) is the basis of the stability of matter and many other phenomena relevant to physics, astrophysics, cosmology, and even biology. It is related to the spin-statistics theorem, and possible violations of this relation have been searched for since its inception. Violations of the PEP may come from various Beyond Standard Model descriptions, including Quantum...
One of the main conundrums of physics is the quantum-to-classical transition. Models of Dynamical wave function Collapse (DCMs) explain it by a progressive reduction of the quantum superposition, proportional to the increase in mass of the system under consideration. Gravity-related collapse models, like the one developed by Diosi and Penrose (DP), aroused growing interest in the last decades,...
