Composite Hybrid Inflation: Dilaton and Waterfall Pions

Autor: Cacciapaglia, Giacomo, Cheong, Dhong Yeon, Deandrea, Aldo, Isnard, Wanda, Park, Seong Chan

We investigate the possibility that inflation originates from a composite field theory, in terms of an effective chiral Lagrangian involving a dilaton and pions. The walking dynamics of the theory constrain the potential in a specific way, where the

Thin-Walled Higgs Assisted Q-balls from Pseudo-Nambu-Goldstone Bosons

Autor: Bishara, Fady Adibsamy, Lennon, Olivier

We consider the question of whether Q-balls can exist in a chiral Lagrangian truncated at leading order when, in addition, the Standard Model Higgs boson couples to the pseudo-Nambu-Golstone bosons (pNGBs). In particular, we consider the so-called th

Conformal anomaly of pseudo-scalar operators

Autor: Chicherin, Dmitry, Sokatchev, Emery

We study the conformal properties of pseudo-scalar (parity-odd) operators in four-dimensional field theory. Such operators include the topological term in a gauge theory and the Yukawa coupling. We show that a single operator of this type cannot be a

The electroweak sector of the Standard Model can be formulated in a way similar to Chiral Perturbation Theory (ChPT), but extended by a singlet scalar. The resulting effective field theory (EFT) is called Higgs-Electroweak Chiral Lagrangian (EWCh$\ma
