Brazilian Report on Dark Matter 2024
I. F. M. Albuquerque, J. Alcaniz, A. Alves +51
One of the key scientific objectives for the next decade is to uncover the nature of dark matter (DM). We should continue prioritizing targets such as weakly-interacting massive pa…
Cosmological phase transitions from the functional measure
Bruno Berganholi, Gláuber C. Dorsch, Iberê Kuntz +2
We investigate how competitive gravitational wave detectors can be to current and near-future colliders in probing a model where the new physics is completely encapsulated in a mod…
Non-singular solutions to the Boltzmann equation with a fluid Ansatz
Gláuber C. Dorsch, Thomas Konstandin, Enrico Perboni +1
Cosmological phase transitions can give rise to intriguing phenomena, such as baryogenesis or a stochastic gravitational wave background, due to nucleation and percolation of vacuu…
Symmetries in particle physics: from nuclear isospin to the quark model
Bruno Berganholi, Gláuber C. Dorsch, Beatriz M. D. Sena +1
We present a concise pedagogic introduction to group representation theory motivated by the historical developments surrounding the advent of the Eightfold Way. Abstract definition…
Vacuum Stability in the one-loop approximation of a 331 Model
G. C. Dorsch, A. A. Louzi, B. L. Sánchez-Vega +1
In this study, we analyze the vacuum stability of the economical 331 model at the one-loop level using the renormalization group equations and a single-scale renormalization method…
Bubble wall velocities with an extended fluid Ansatz
Glauber C. Dorsch, Daniel A. Pinto
We compute the terminal bubble wall velocity during a cosmological phase transition by modelling non-equilibrium effects in the plasma with the so-called "extended fluid Ansatz". A…
Probing a Dark Sector with Collider Physics, Direct Detection, and Gravitational Waves
Giorgio Arcadi, Glauber C. Dorsch, Jacinto P. Neto +2
We assess the complementarity between colliders, direct detection searches, and gravitational wave interferometry in probing a scenario of dark matter in the early universe. The mo…
A sonic boom in bubble wall friction
Glauber C. Dorsch, Stephan J. Huber, Thomas Konstandin
We revisit the computation of bubble wall friction during a cosmological first-order phase transition, using an extended fluid Ansatz to solve the linearized Boltzmann equation. A…
Bubble wall velocities in the Standard Model and beyond
Glauber C. Dorsch, Stephan J. Huber, Thomas Konstandin
We present results for the bubble wall velocity and bubble wall thickness during a cosmological first-order phase transition in a condensed form. Our results are for minimal extens…
The Higgs Vacuum Uplifted: Revisiting the Electroweak Phase Transition with a Second Higgs Doublet
G. C. Dorsch, S. J. Huber, K. Mimasu +1
The existence of a second Higgs doublet in Nature could lead to a cosmological first order electroweak phase transition and explain the origin of the matter-antimatter asymmetry in…
Hierarchical vs Degenerate 2HDM: The LHC Run 1 Legacy at the Onset of Run 2
G. C. Dorsch, S. J. Huber, K. Mimasu +1
Current discussions of the allowed two-Higgs-doublet model (2HDM) parameter space after LHC Run 1 and the prospects for Run 2 are commonly phrased in the context of a quasi-degener…
More Higgses at the LHC and the Electroweak Phase Transition
G. C. Dorsch, S. J. Huber, K. Mimasu +1
A cosmological first order electroweak phase transition could explain the origin of the cosmic matter-antimatter asymmetry. While it does not occur in the Standard Model, it become…
Echoes of the Electroweak Phase Transition: Discovering a second Higgs doublet through
G. C. Dorsch, S. Huber, K. Mimasu +1
The existence of a second Higgs doublet in Nature could lead to a cosmological first order electroweak phase transition and explain the origin of the matter-antimatter asymmetry in…
Cosmological Signatures of a UV-Conformal Standard Model
Glauber C. Dorsch, Stephan J. Huber, Jose Miguel No
Quantum scale invariance in the UV has been recently advocated as an attractive way of solving the gauge hierarchy problem arising in the Standard Model. We explore the cosmologica…
A strong electroweak phase transition in the 2HDM after LHC8
G. C. Dorsch, S. J. Huber, J. M. No
The nature of the electroweak phase transition in two-Higgs-doublet models is revisited in light of the recent LHC results. A scan over an extensive region of their parameter space…
