10:00 Cutting operators with MATCHETE: automatic reduction to a minimal EFT basis and treatment of evanescent operators

MATCHETE is a Mathematica program designed to automate the one-loop matching of a generic weakly-coupled UV theory to its corresponding Effective Field Theory (EFT) where heavy modes have been integrated out. By relying on functional methods, the matching process is very systematic and well-suited for computer execution. On the other hand, reduction of the obtained result to a minimal EFT basis, using integration by parts, reduction of Dirac and group structures, fierz identities and field redefinitions, present several challenges for the automation. In particular, evanescent operators appearing at one-loop from tree-level matching need to be addressed.
After describing the working principles of Matchete, I will present its current and future functionalities and demonstrate its application using a toy model.

11:15 Adding Flavors to Axiogenesis and Spicing Up Cosmological Mysteries

A rotation in Peccei-Quinn field space along the axion direction can address cosmological mysteries, including dark matter, baryon asymmetry, cosmic perturbations, and the Hubble tension. This dynamics may naturally arise as a result of quantum gravity effects and cosmic inflation. Axion rotations can simultaneously give a new origin of axion dark matter via kinetic misalignment and generate the observed excess of matter over antimatter in the Universe via axiogenesis. For ultralight (QCD) axions, this cogenesis scenario predicts axion properties more experimentally accessible than the conventional ones. For heavy and cosmologically unstable QCD axions, predictions from axiogenesis point to regions that can be probed by neutrino experiments and long-lived particle searches. In this talk, we will provide an overview of this paradigm and discuss exciting potential connections to flavor physics.

11:15 Searching for light accelerated dark matter

Low mass accelerated dark matter (DM) is very well motivated and has been a subject of much attention in the literature. These fast-moving particles can gain enough kinetic energy to surpass the energy thresholds of some Large volume terrestrial detectors. For instance, fast-moving DM can deposit sizable amounts of energy at both large volume neutrino detectors and dark matter direct detection experiments. In this talk, I will focus on searches for both multi-component "boosted" DM and cosmic-ray accelerated DM. I will present recent and on-going work which explores these accelerate DM scenarios using a variety of probes.

14:00 Flavonic dark matter

We present a common solution to dark matter and the flavor problem n the framework of the discrete flavor symmetry.

where the associated flavonic Goldstone boson acts as a good dark matter candidate through the misalignment mechanism.

For light active neutrinos, the Dirac-type mass matrix is preferred to fit the observed neutrino oscillation data with normal hierarchy.

Our model predicts the axion-like photon coupling characteristically different from the standard QCD axion, and only two limited coners of

the parameter space can be probed by the future X-ray and radio observations, respectively.

I will provide a brief introduction of neutrinos and some results. Thereafter, I will use Neutrino non-standard interaction (NSI) as a beyond the standard model scenario to see its effects in the upcoming long baseline neutrino experiments DUNE and T2HK. One can find that the NSI can spoil the clean determination of the standard neutrino parameters. I will also comment on the implications of NSI in LFV muon decays and conclude with some remarks.

15:15 Flavour in Finite SU(5) Grand Unified Theories

We study four SU (5) supersymmetric models which exhibit S3 and/or ZN
symmetries, that are finite to two or all loops and their corresponding mass
matrices. Some of the models have viable mass textures, like the Nearest Neighbour
Interaction one. In particular, an all-loop finite model was identified, which
has a significant parameter reduction and could reproduce the observed quark
masses and mixing pattern. In this case the finiteness conditions determine the absolute value of the Yukawa couplings at the
unification scale, although not the Higgs vevs. For the two-loop finite models, a range of values
for the Yukawa couplings is also found. We include an analysis of the number
and position of the phases, not previously done in Finite Unified Theories,
which contributes towards the reduction of parameters.

10:45 Implication of A4 modular symmetry on neutrino masses, mixing and leptogenesis

Motivated by the crucial role played by the discrete flavour symmetry groups in explaining the
observed neutrino oscillation data, we consider the application $A_4$ modular symmetry in the
linear seesaw framework. The basic idea behind using the modular symmetry is to minimize the
necessity of the inclusion of extra flavon fields having specific vacuum expectation value (VEV) alignments.
The breaking of flavor symmetry takes place when the complex modulus $\tau$ acquires VEV.
The main issue of the perplexing vacuum alignment is avoided, the only requirement is a certain
kind of mechanism which can fix the modulus $\tau$. The non-trivial transformation of Yukawa
couplings under the $A_4$ modular symmetry helps to explore the neutrino phenomenology with
a specific flavor structure of the mass matrix. We discuss the phenomena of neutrino mixing and also
show the non-zero CP asymmetry from the decay of lightest heavy fermion superfield to explain
the preferred phenomena of baryogenesis through leptogenesis including flavor effects.

14:45 The flavor of a string

We explore the flavor symmetries emerging from string model building and their phenomenological consequences. We point out that there is only a small set of admissible flavor symmetries, where both modular and traditional symmetries appear and strong constraints on the flavor representations and other properties gover automatically the effective action. These findings may be considered as top-down guiding principles for bottom-up model building in the search of a solution of the flavor puzzle.

09:30 Composite matter/antimatter hadron structure indicated experimentally at Texas Petawatt Laser Facility

It has been theorized that, at the Universe’s inception, there were equal amounts of matter and antimatter. One of the great mysteries of modern physics is the asymmetry between the amount of matter and the amount of antimatter apparent in the Universe. Here it is shown that, when a high-energy laser strikes a gold target, the gold is transmutated to platinum. This experimental result indicates that hadrons are actually composite particles containing both matter and antimatter. The implications of this new model of hadron structure are significant, impacting our understanding of cosmology, proton-proton chain reactions in stars, the expansion of the Universe, and beta decay in radioactive isotopes, among other key topics in physics.
