41. A Critical Examination of the Standard Model of Particle Physics

Dr Eliahu Comay

In this talk I focus on the coherence of the present theories of electromagnetic, strong, and weak interactions that comprise the three sectors of the Standard Model of particle physics. The analysis performed, provides us with high confidence that well-established physical laws yield useful acceptability criteria for a given quantum field theory. In particular, radiation and bound fields of...

40. Neural Networks for solving fundamental Differential Equations of Physical Significance with focus on the Dirac Equation

Athanasios Gkrepis (University of Ioannina)

In this work we discuss a Neural Networks scheme falling in the category of the Physics Informed Neural Networks (PINN), that has recently aroused the intense interest among the researchers. After discussing the state of the art of the topic we focus on some important applications that are connected to the fundamental Differential Equations of Physical Significance (such as the Schrödinger,...

38. Object Oriented Structuring of Physics Informed Neural Network Solvers

Dr Angelos Giotis (University of Ioannina)

In this work, we present an end-to-end system leveraging neural networks for objective function optimization in solving the Schrödinger and Dirac Differential Equations. We propose an object-oriented Python programming framework, enabling dynamic adaptation of user input for solving such equations via tunable hyper-parameters. This framework facilitates testing of various network architectures...

20. Quest for New physics of Charged Lepton Flavor Violation ; The COMET experiment at J-PARC

Yoshitaka KUNO

Charged Lepton Flavor Violation (CLFV) is as one of prime arena for probing new physics beyond the Standard Model (BSM), given its rate being highly suppressed in the SM, yet substantial predictions on the rate in new physics models. Notably, muon to electron conversion in a muonic atom serves as a promising process in this exploration. The upcoming COMET experiment in Japan, characterized by...

24. Searching for dark matter axions via atomic excitations

Prof. John Vergados (University of Ioannina)

Axions can be considered as good dark matter candidates. The detection of such light particles can be achieved by observing axion spin induced atomic excitations. The target is in a magnetic field so that the m-degeneracy is removed the energy levels can be suitably adjusted. Using an axion-electron coupling indicated by the limit obtained by the Borexino experiment, which is quite stringent,...

29. The Mu2e experiment

Stefano Di Falco (Universita & INFN Pisa (IT))

The Mu2e experiment, currently under construction at Fermilab, will search for neutrinoless mu->e conversion in the field of an aluminum atom. A clear signature of this charged lepton flavor violating two-body process is given by the monoenergetic conversion electron of 104.97 MeV produced in the final state.

An 8 GeV/c pulsed proton beam interacting on a tungsten target will produce the...
