Lorentz Invariance Violation effects on UHECR propagation: a geometrized approach
M. D. C. Torri, S. Bertini, M. Giammarchi +1
We explore the possibility to geometrize the interaction of massive fermions with the quantum structure of space-time, trying to create a theoretical background, in order to explai…
Conformal structure of the Schwarzschild black hole
Stefano Bertini, Sergio L. Cacciatori, Dietmar Klemm
We show that the scalar wave equation at low frequencies in the Schwarzschild geometry enjoys a hidden SL(2,R) invariance, which is not inherited from an underlying symmetry of the…
On the Euler angles for SU(N)
S. Bertini, S. L. Cacciatori, B. L. Cerchiai
In this paper we reconsider the problem of the Euler parametrization for the unitary groups. After constructing the generic group element in terms of generalized angles, we compute…
