KM3NeT/ORCA: Unveiling Neutrino Secrets
The KM3NeT/ORCA neutrino telescope, located in the Mediterranean Sea, aims to measure the neutrino mass hierarchy using atmospheric neutrinos. Its innovative design utilizes a tridimensional array of PhotoMultiplier Tubes (PMTs) within Digital Optical Modules (DOMs) arranged along vertical detection units (DUs).
The telescope captures Cherenkov photons emitted by charged particles resulting from neutrino interactions. These light pulses, with their precise position and timing information, are critical for reconstructing neutrino event kinematics. However, raw light patterns present a significant challenge for traditional reconstruction methods, as physics insights are not intrinsically known to the models.

Transformers: A Leap Forward for KM3NeT/ORCA
This research confirms that cutting-edge deep learning models like transformers, when enhanced with physics and detector-inspired attention masks, deliver significant improvements in neutrino reconstruction for the KM3NeT/ORCA telescope simulations.
Compared to traditional maximum-likelihood fit algorithms, transformers achieve better direction and energy resolution, particularly at low energies—a critical factor for studying neutrino oscillations. Furthermore, the strategic use of pre-trained models from larger configurations proves invaluable for a detector still under construction, retaining essential physics information and substantially reducing training costs.
