Model-independent machine learning approach for nanometric axial localization and tracking
/ Alexandrov, Andrey (INFN, Naples) ; Acampora, Giovanni (INFN, Naples ; U. Naples (main)) ; De Lellis, Giovanni (INFN, Naples ; U. Naples (main) ; CERN) ; Di Crescenzo, Antonia (INFN, Naples ; U.

Accurately tracking particles and determining their coordinate along the optical axis is a major challenge in optical microscopy, especially when extremely high precision is needed. In this study, we introduce a deep learning approach using convolutional neural networks (CNNs) that can determine axial coordinates from dual-focal-plane images without relying on predefined models.

Yb-based high-power frequency combs for high-intensity laser–particle interactions
/ Roiková, Eva (CERN ; Uppsala U.) ; Martens, Aurélien (IJCLab, Orsay) ; Latina, Andrea (CERN) ; Goryashko, Vitaliy (Uppsala U. ; XFEL, RIKEN) ; Krasny, Mieczyslaw Witold (CERN ; LPNHE, Paris) ; Chulkov, Ruslan (Uppsala U.) ; Goddard, Brennan (CERN) ; Musat, Vlad (CERN ; JAI, UK) ; Granados, Eduardo (CERN)
Optical frequency combs (OFCs) are a revolutionary tool for metrology, spectroscopy, and, in general, the precise interaction of lasers with particles. In this context, ytterbium (Yb) based laser technologies are particularly relevant due to their broad bandwidth and ability to produce high average power laser beams at extremely low phase-noise level.

Theoretical overview on heavy flavor physics at LHCb
/ Shen, Yue-Long (Ocean U.)
Precise prediction of the heavy hadrons decay amplitudes is of great importance in the determination of the parameters of KM matrix and searching for new physics signals beyond the standard model. Due to the high accuracy of the B meson decay constants, the structure dependent QED corrections should be taken into account for B→μ+μ− decays due to the power enhancement, but this effect is numerically negligible for B→τ+τ−.
