The pion, and specifically its charge form factor, is of key interest in the study of the quark-gluon structure of hadrons. This is exemplified by the many calculations that treat the pion as one of their prime examples. One of the reasons is that the valence structure of the pion, being 〈qq̄〉, is relatively simple. Hence it is expected that the value of the four-momentum transfer squared Q, dow...

We assume that the Pauli exclusion principle is violated for neutrinos, and consequently, neutrinos obey the Bose-Einstein statistics. Cosmological and astrophysical consequences of this assumption are considered. Neutrinos may form cosmological Bose condensate which accounts for all (or a part of) the dark matter in the universe. “Wrong” statistics of neutrinos could modify big bang nucleosynt...

Jacket matrices motivated by the center weight Hadamard matrices have played an important role in signal processing, communications, image compression, cryptography, etc. In this paper, we suggest a design approach for the Pauli block jacket matrix achieved by substituting some Pauli matrices for all elements of common matrices. Since, the well-known Pauli matrices have been widely utilized for...

We compute the electromagnetic charged kaon form factor in time-like region by employing a Poincar\'e covariant formalism of Bethe-Salpeter equation to study quark-antiquark bound states conjunction with Schwinger-Dyson for quark propagator. Following recent kindred calculation pion factor, we include most relevant intermediate composite particles permitted their quantum numbers interaction ker...
