Is nature natural?
Alessandro Strumia
I summarize the apparent relevance of anthropic selection in understanding unnatural features of the Standard Model, and the consequent implications for theory. This topic, pioneer…
Gravitational waves and black holes from the phase transition in models of dynamical symmetry breaking
Martín Arteaga, Anish Ghoshal, Alessandro Strumia
Theories of dynamical electroweak symmetry breaking predict a strong first order cosmological phase transition: we compute the resulting signals, primordial black holes and gravita…
Cosmological collider non-Gaussianity from multiple scalars and gravity
Shuntaro Aoki, Anish Ghoshal, Alessandro Strumia
Cosmological collider signals of primordial non-Gaussianity arise at tree level when an extra scalar has Hubble mass during inflation. We critically review the formalism finding th…
Solving the strong CP problem without axions
Ferruccio Feruglio, Matteo Parriciatu, Alessandro Strumia +1
We formulate general conditions under which the strong CP problem is solved by spontaneous CP violation. Quark-mass matrix elements are polynomials in the CP-breaking order paramet…
