The photo-philic QCD axion
Marco Farina, Duccio Pappadopulo, Fabrizio Rompineve +1
We propose a framework in which the QCD axion has an exponentially large coupling to photons, relying on the "clockwork" mechanism. We discuss the impact of present and future axio…
Energy helps accuracy: electroweak precision tests at hadron colliders
Marco Farina, Giuliano Panico, Duccio Pappadopulo +3
We show that high energy measurements of Drell-Yan at the LHC can serve as electroweak precision tests. Dimension-6 operators, from the Standard Model Effective Field Theory, modif…
Phases of Cannibal Dark Matter
Marco Farina, Duccio Pappadopulo, Joshua T. Ruderman +1
A hidden sector with a mass gap undergoes an epoch of cannibalism if number changing interactions are active when the temperature drops below the mass of the lightest hidden partic…
Cannibal Dark Matter
Duccio Pappadopulo, Joshua T. Ruderman, Gabriele Trevisan
A thermally decoupled hidden sector of particles, with a mass gap, generically enters a phase of cannibalism in the early Universe. The Standard Model sector becomes exponentially…
