Powerful Yukawas
Timothy Cohen, Matthew McCullough, Neal Weiner
We introduce a class of models where the masses of the light Standard Model fermions are due to an Effective Field Theory operator that appears beyond dimension-4 in the power coun…
pNGB Higgs Naturalness at a Tipping Point
Matthew McCullough, Adriana Menkara, Ennio Salvioni
In scenarios where the Higgs is viewed as a pseudo Nambu-Goldstone boson (pNGB) the question of naturalness finds itself, from a phenomenological perspective, at a tipping point be…
In Pursuit of New Paradigms: TASI 2024
Matthew McCullough
These lectures discuss diverse theoretical approaches, old and new, towards understanding the origin of the Higgs sector of the Standard Model and the lightness of the Higgs boson.
Phases of Pseudo-Nambu-Goldstone Bosons
Fotis Koutroulis, Matthew McCullough, Marco Merchand +2
We study the vacuum dynamics of pseudo-Nambu-Goldstone bosons (pNGBs) for spontaneous and explicit symmetry breaking. We determine the magnitude of expl…
