Large primordial fluctuations in gravitational waves from phase transitions

Journal of High Energy Physics, 2023
It is well-known that first-order phase transitions in the early universe can be a powerful source of observable stochastic gravitational wave backgrounds.

Probing primordial black holes from a first order phase transition through pulsar timing and gravitational wave signals

Journal of High Energy Physics, 2023
In this work, we assess the sensitivity reach of pulsar timing array (PTA) measurements to probe pointlike primordial black holes (PBHs), with an extended mass distribution, which originate from collapsed Fermi balls that are formed through the ...

The supercooling window at weak and strong coupling

Journal of High Energy Physics, 2023
Supercooled first order phase transitions are typical of theories where conformal symmetry is predominantly spontaneously broken. In these theories the fate of the flat scalar direction is highly sensitive to the size and the scaling dimension of the ...

Phase Transitions in the Universe [PDF]

, 1998
During the past two decades, cosmologists turned to particle physics in order to explore the physics of the very early Universe. The main link between the physics of the smallest and largest structures in the Universe is the idea of spontaneous symmetry ...

Topological Defects and Cosmology [PDF]

, 1998
Many particle physics models of matter admit solutions corresponding to stable or long-lived topological defects. In the context of standard cosmology it is then unavoidable that such defects will form during phase transitions in the very early Universe.

Doubly peaked induced stochastic gravitational wave background: testing baryogenesis from primordial black holes

Journal of High Energy Physics, 2022
Hawking evaporation of primordial black holes (PBHs) can facilitate the generation of matter-antimatter asymmetry. We focus on ultra-low mass PBHs that briefly dominate the universe and evaporate before the big bang nucleosynthesis.

Inflation, electroweak phase transition, and Higgs searches at the LHC in the two-Higgs-doublet model

Journal of High Energy Physics, 2022
Combining the Higgs searches at the LHC, we study the Higgs inflation in the type-I and type-II two-Higgs-doublet models with non-minimally couplings to gravity.

Axion inflation in the strong-backreaction regime: decay of the Anber-Sorbo solution

Journal of High Energy Physics, 2023
Axion inflation coupled to Abelian gauge fields via a Chern-Simons-like term of the form ϕF F ~ $$ \phi F\overset{\sim }{F} $$ represents an attractive inflationary model with a rich phenomenology, including the production of magnetic fields, black holes,

LHC and ILC Data and the Early Universe Properties [PDF]

, 2009
With the start-up of the LHC, we can hope to find evidences for new physics beyond the Standard Model, and particle candidates for dark matter. Determining the parameters of the full underlying theory will be a long process requiring the combination of ...
