We considered spin-two gauge boson production in the fermion pair annihilation process and calculated the polarized cross-sections for each set of helicity orientations of initial and final particles. Adding up all sixteen amplitudes and... more
In the non-Abelian tensor gauge field theory a lower-rank field is represented by a general nonsymmetric tensor and describes the propagation of charged bosons of helicities two and zero. We clarify and prove this result from different... more
We consider the production of charged spin-two gauge bosons in the gluon-gluon scattering and calculate polarised cross sections for each set of helicity orientations of initial and final particles. The angular dependence of this cross... more
Η παρούσα μελέτη επιχειρεί να παρουσιάσει τις ιστορικές διακτινώσεις μιας έννοιας που τυγχάνει ευρύτατης χρήσης στην καθημερινή πρακτική, διαδραματίζει κεντρικό ρόλο στις σύγχρονες επιστημονικές έρευνες και έχει διανοίξει ένα πεδίο... more
We investigate metric independent, gauge invariant and closed forms in the generalized YM theory. These forms are polynomial on the corresponding fields strength tensors - curvature forms and are analogous to the Pontryagin-Chern... more
We assume that inside the hadrons there are additional partons - tensorgluons - which carry the same charges as the gluons, but have larger spin. That assumption leads to a possible contribution of polarised tensorgluon density to the... more
Οι σημειώσεις αυτές αποτελούν μια αυτοτελή μελέτη της Φυσικής των Στοιχειωδών Σωματιδίων και των Αλληλεπιδράσεων. Οι θεμελιακές αρχές της θεωρίας αναλύονται διεξοδικά και εφαρμόζονται για να κατασκευαστεί το Καθιερωμένο Πρότυπο (Standard... more
We define two a priori tests of pseudo-random number generators for the class of linear matrix-recursions. The first desirable property of a random number generator is the smallness of serial or lagged correlations between generated... more
Οι σημειώσεις αφορούν μάθημα προχωρημένης Κβαντικής Μηχανικής. Η ανάπτυξη της θεωρίας ακολουθεί μια ομαδο-θεωρητική κατεύθυνση. Αφού αναλυθούν οι αναπαραστάσεις της ομάδας Poincare, διατυπώνεται η εξίσωση του Dirac και φανερώνονται οι... more
A systematic method is presented for the construction and classification of algebras of gauge transformations for arbitrary high rank tensor gauge fields. For any tensor gauge field of a given rank, the gauge transformation will be... more
In the gauge theoretic approach of gravity, General Relativity is described by gauging the symmetry of the tangent manifold in four dimensions. Usually the dimension of the tangent space is considered to be equal to the dimension of the... more
