James Daniel Wells (University of Michigan (US))22/04/2024, 10:00Invited Talk
For decades naturalness and finetuning considerations have been important factors in the work of theoretical particle physics. I explain how such considerations fit into the broader scheme of methods of theoretical particle physics. I then formalize the intuitions of particle physicists over the decades within effective field theory language and justify several assertions along the way: the...

In my talk I will discuss the first order phase transitions with fast bubbles. Particular attention will be paid to the heavy fields production and its applications for the non thermal Dark Matter production and baryogenesis.

The Tunneling Potential formalism offers an alternative to the Euclidean bounce approach for calculating tunneling actions, which govern the exponential suppression of metastable vacua decay in quantum field theory. In this talk, I will discuss how this formalism elegantly describes gravitational effects on vacuum decay, bubble-of-nothing decays, domain walls, and more.

After introducing the general concept of flavoured dark matter, in this talk I will focus on a specific model of flavoured Majorana dark matter. I will provide a review of the constraints coming from flavour physics and direct and indirect detection constraints. I will then focus on different possible scenarios for dark matter freeze-out and their implications for collider phenomenology.

The Two Higgs Doublet Model invariant under the gauge group SU (2) ร U (1) is known to have six additional global discrete or continuous symmetries of its scalar sector. We have discovered regions of parameter space of the model which are basis and renormalization group invariant to all orders of perturbation theory in the scalar and gauge sectors, but correspond to none of the hitherto...

Topological defects can play an important role in cosmology. In this talk I will discuss a less explored effect that arises in the context of first order phase transitions, by which defects can act as local impurities catalysing the decay of the false vacuum. This dynamics takes place in one of the simplest extensions of the Standard Model, the xSM, where domain wall configurations associated...

We review models of partial compositeness constructed using ordinary four-dimensional gauge theories with fermionic matter. We show that they give rise to a set of collider signatures of interest for the high luminosity run of LHC (mostly light scalars with low production cross-sections). We also discuss some observables that need to be computed on the lattice in order to establish the...

We revisit the stability analysis of the Standard Model Higgs potential, using both the highest theoretical precision and the most accurate determination of input parameters to date. The stability of the electroweak vacuum is found to be subject to the top mass and the strong coupling constant, and we discuss the impact of their central values and uncertainties in detail.

Dr Florian NORTIER (CNRS - IP2I Lyon)24/04/2024, 12:00Talk
Inspired by tower truncation in string field theory, weakly nonlocal (WNL) quantum field theories (QFT's) have been proposed to soften the UV behavior in particle physics for naturalness and quantum gravity. Pseudo-differential form factors preclude the appearance of pathological ghosts in the particle spectrum, contrary to local higher-derivative field theories ร la Lee-Wick. However, when...

I will discuss phenomenological aspects of the 2HDM+a model complemented wth a fermionic Dark Matter candidate. I will show how the model complies with Dark Matter Phenomenology, can provide an interpretation of some recent experimental anomalies and, finally, can account for GW signals from a First Order Phase Transition in the Early Universe.

I present a new principle of relativity in physics.
Go to contribution page
It is an alternative away from naturalness towards a new
paradigm.
It allows for an a priori derivation of the gauge structure of nature.
In particular it can explain why there are precisely three generations
of fermions.
A specific form of dark matter is preferred.
The standard model can only be extended in a minimalistic way. -
Avelino Vicente (IFIC - CSIC / U. Valencia)24/04/2024, 12:45Talk
I discuss a grand unified theory that assigns a separate $SU(5)$ gauge group to each fermion family. The equality of the gauge couplings at the unification scale is enforced by means of a cyclic $\mathbb{Z}_3$ symmetry. Such tri-unification reconciles the idea of gauge non-universality with gauge coupling unification, opening the possibility to build consistent non-universal descriptions of...

The existence of light, weakly-interacting new particles beyond the Standard Model is a well-motivated alternative to new particles existing at the TeV scale or beyond. With the example of axion-like particles (ALPs), which offer an explanation of the puzzling absence of the electric dipole moment of the neutron, we discuss the current status of both direct searches at the LHC and in flavor...

Gravitational waves provide a new window into the early Universe, and thus a new way of probing the dynamics of dark sectors. I will provide an overview of primordial gravitational wave sources, highlight what we have learned recently and speculate about possible future insights.

Hooman Davoudiasl26/04/2024, 10:30Invited Talk
Weaker gravity during an early epoch would yield a smaller Hubble rate, which is the measure of efficiency for primordial processes. A slower cosmic tempo can accommodate alternative cosmological histories. We consider this possibility for thermal relic dark matter, in the context of extra dimensional models. These models could potentially alleviate the hierarchy problem and may be testable...

In the setup of a warped extra dimension we have proposed a far IR brane, at the GeV scale, with a conformal sector confining at a first order phase transition, and generating a stochastic gravitational waves background which can accommodate the recent NANOGrav signal. If dark matter is localized in the dark brane, it has only gravitational interactions with the Standard Model: it can easily...
