Artificial Neural Network as a FPGA Trigger for a Detection of Neutrino-Induced Air Showers
; Głas, Dariusz; (IntechOpen, 2016)
Neutrinos play a fundamental role in the understanding of the origin of ultrahigh-energy cosmic rays (UHECR). They interact through charged and neutral currents in the atmosphere generating extensive air showers. However, ... -
Lorentz-covariant, unitary evolution of a relativistic Majorana qubit
Smoliński, Kordian; ; ; (Springer Nature, 2018)
We formulate a covariant description of a relativistic qubit identified with an irreducible set of quantum spin states of a Majorana particle with a sharp momentum. We treat the particle’s four-momentum as an external ... -
An analysis method for data taken by Imaging Air Cherenkov Telescopes at very high energies under the presence of clouds
