The energy budget for gravitational waves of a cosmological first order phase transitions depends on the speed of sound in the thermal plasma in both phases around the

Status of Electroweak Baryogenesis in Minimal Composite Higgs

Autor: Bruggisser, Sebastian, von Harling, Benedict, Matsedonskyi, Oleksii, Servant, Geraldine

We present an update on the status of electroweak baryogenesis in minimal composite Higgs models. The particularity of this framework is that the electroweak phase transition can proceed simultaneously with the confinement phase transition of the new

Journal of High Energy Physics

We present a comprehensive study of the electroweak phase transition in composite Higgs models, where the Higgs arises from a new, strongly-coupled sector which confines near the TeV scale. This work extends our study in Ref. [1]. We describe the con

High-Temperature Electroweak Symmetry Non-Restoration from New Fermions and Implications for Baryogenesis

Autor: Oleksii Matsedonskyi, Geraldine Servant

The strength of electroweak symmetry breaking may substantially differ in the early Universe compared to the present day value. In the Standard Model, the Higgs vacuum expectation value (vev) vanishes and electroweak symmetry gets restored at tempera

A first-order electroweak phase transition from varying Yukawas

Physics letters / B 786, 373-377 (2018). doi:10.1016/j.physletb.2018.10.015

We show that the dynamics responsible for the variation of the Yukawa couplings of the Standard Model fermions generically leads to a very strong first-order electroweak phase transition, assuming that the Yukawa couplings are large and of order 1 be

The Hierarchy Problem and the Cosmological Constant Problem Revisited

Autor: Jegerlehner, Fred

Publikováno v: Foundations of physics 49(9), 915-971 (2019). doi:10.1007/s10701-019-00262-2

We argue that the Standard Model (SM) in the Higgs phase does not suffer from a “hierarchy problem” and that similarly the “cosmological constant problem” resolves itself if we understand the SM as a low energy effective theory emerging from

High scale electroweak phase transition: baryogenesis & symmetry non-restoration

Journal of High Energy Physics
Journal of high energy physics 1810(10), 053 (2018). doi:10.1007/JHEP10(2018)053

We explore the possibility that the electroweak phase transition happens at a scale much higher than the electroweak scale today. In this context, high scale CP-violating sources for electroweak baryogenesis are not constrained by low-energy experime

Probing the electroweak phase transition via enhanced di-Higgs boson production

Autor: Marcela Carena, Zhen Liu, M. Riembau

Publikováno v: Physical Review
Physical review / D 97(9), 095032 (2018). doi:10.1103/PhysRevD.97.095032

We consider a singlet extension of the standard model (SM) with a spontaneous Z2 breaking and study the gluon-gluon fusion production of the heavy scalar, with subsequent decay into a pair of SM-like Higgs bosons. We find that an on-shell interferenc

The Baryon Asymmetry from a Composite Higgs

Autor: Bruggisser, Sebastian, Von Harling, Benedict, Matsedonskyi, Oleksii, Servant, Géraldine

We study the nature of the electroweak phase transition (EWPT) in models where the Higgs emerges as a pseudo-Nambu-Goldstone boson of an approximate global symmetry of a new strongly-interacting sector confining around the TeV scale. Our analysis foc
