Composite Hybrid Inflation : Primordial Black Holes and Stochastic Gravitational Waves
Giacomo Cacciapaglia, Dhong Yeon Cheong, Aldo Deandrea +4
We investigate the production of primordial black holes and gravitational waves in composite hybrid inflation. Starting from an effective chiral Lagrangian with a dilaton and pions…

One loop renormalization of 5D gauge-Yukawa theories
Giacomo Cacciapaglia, Wanda Isnard, Roman Pasechnik +1
The common lore dictates that extra dimensional theories loose predictive power at energies just above the compatification scale, due to the power-law running of bulk coupling. We…

Are there minimal exceptional aGUTs from stable 5D orbifolds?
Giacomo Cacciapaglia, Alan S. Cornell, Aldo Deandrea +4
In analysing five dimensional orbifolds with exceptional gauge groups, we seek to find stable vacua configurations which satisfy the minimal requirements for asymptotic grand unifi…
