An obstruction to generalised discrete torsion in string theory
Carlo Angelantonj, Giorgio Leone, Diego Perugini
We reconsider the possibility of turning on generalised discrete torsion in orbifold compactifications, whereby different discrete torsion phases are attached to different fixed po…
TeV-scale leptogenesis in a parity symmetric neutrino mass model
Keisuke Harigaya, Gio Leone
We study leptogenesis via out-of-equilibrium decays of right-handed neutrinos in a parity symmetric extension of the Standard Model with gauge group $SU(3)_c \times SU(2)_L \times…
UV/IR relations from the worldsheet
Christian Aoufia, Ivano Basile, Giorgio Leone +1
We derive universal scaling relations for the low-energy effective action of string theory, connecting the vacuum energy and gauge couplings to higher-derivative Wilson coefficient…
