Dr Otari Sakhelashvili (Sydney University)12/9/24, 10:00โฏAMInvited Talk
In this talk, I will argue that the consistency of non-perturbative $\theta$-vacua in gauge theories and gravity predicts the presence of axion-like particles (ALPs) in the particle spectrum. This prediction also necessitates additional structures in these theories. Specifically, General Relativity incorporates Eguchi-Hanson instantons, which generate gravitational $\theta$-vacua. The...

The Quantum Technologies and Dark Matter research laboratory at the University of Western Australia has a rich history of developing precision tools for testing fundamental physics at low energies. This includes the efforts to discover โBeyond Standard Modelโ physics, including the nature of Dark Matter and the unification of Quantum Mechanics with General Relativity to help uncover a unified...

John Gargalionis (IFIC)12/9/24, 3:30โฏPM
In this talk I will present a general study of nucleon decay based on the SMEFT up to dimension 7. Our analysis takes into account RGE effects, and includes limits on the scale underlying each operator, an assessment of the possibility of flat directions, and correlations between decay modes assuming single-operator dominance. The talk is mainly based on 2312.13361.

We are expecting high-precision observations from upcoming CMB surveys, such as the Simons Observatory, CMB-S4, and LiteBIRD, as well as from surveys of the large-scale structure, such as Rubin LSST, Euclid, DESI, PSF, SPHEREx, and Roman. Most of the observables from these independent surveys will be correlated due to their sky and redshift overlaps. Joint analysis of these surveys will be key...

The search for dark matter (DM) remains one of the most pressing challenges in modern physics. Detecting sub-GeV DM particles poses significant challenges for traditional Earth-based detectors due to their low collision energies. This talk presents a novel approach to overcome these limitations: blazar-boosted dark matter (BBDM). I will explore how active galactic nuclei (AGN) with jets...

Prof. Nicole Bell (The University of Melbourne)12/10/24, 11:00โฏAMContributed Talk
We consider the capture of dark matter in neutron stars, and the heating caused by the subsequent thermalization and annihilation of that dark matter. We find that most of the dark matterโs kinetic energy is rapidly deposited in the star. We also discuss, for the first time, the annihilation of partially thermalized dark matter. We find that capture-annihilation equilibrium, and hence...

I discuss paradoxical situation in detection of the highest energy cosmic rays by Telescope Array and Pierre Auger experiments, in particular, a strong discrepancy between their results for cosmic ray fluxes at energies above the GZK cutoff. I also discuss ideas of new BSM physics and dark matter identity which could naturally resolve these paradoxes.

We propose a scenario for cogenesis of baryon asymmetry and dark matter driven by Majoron. It can be achieved assuming either an initial kinetic motion or a conventional misalignment with symmetry non-restoration.

(i) The recent excess in a rare decay of the Higgs boson $H\to Z \gamma$ can be interpreted using a light axion-like particle (ALP) in the mass range of $0.05 - 0.1$ GeV. The dominant decay of such a light ALP is into a pair of collimated photons, whose decay is required to happen before reaching the ECAL detector, such that it mimics a single photon in the... -

The ultra-cold muon technology developed for the muon g โ 2 experiment at J-PARC provides a low-emittance mu+ beam which can be accelerated and used for realistic collider experiments. We consider the possibility of new collider experiments by accelerating the mu+ beam up to 1 TeV. Allowing the mu+ beam to collide with a high-intensity eโ beam at the TRISTAN energy, 30 GeV, in a storage ring...

Neutrinos are known to play crucial roles in core-collapse supernova explosions. The anticipated large amount of supernova neutrinos events from the next galactic explosion as well as the upcoming unambiguous detection of the diffuse supernova neutrino background are also expected to be important messengers to probe various important issues in astrophysical, nuclear, and particle physics....

The Hyper-Kamiokande project in Japan envisions a broad experimental program, including the discovery of charge-parity violation in neutrino oscillation, the search for nucleon decay and (indirectly) dark matter, and supernova neutrinos. This talk will describe the current status and efforts towards realizing this next generation experiment.

Julia Gehrlein (Colorado State University (US))12/12/24, 9:30โฏAMInvited Talk
The observation of neutrino oscillations has shown that neutrinos are massive and hence that the Standard Model of particle physics has to be extended. In this talk I will discuss recent developments in neutrino theory which can guide experimental explorations of the neutrino sector.

In slow-roll inflationary models, the inflaton can undergo excursions on the order of the Planck scale, leading to significant changes in the properties of fields coupled to the inflaton, referred to as spectator fields. These changes may result in transitions between weakly and strongly interacting regimes, or even alterations in mass squared within the spectator field sector during...

We will discuss the models beyond the Standard Model (BSM) consisting of inverse seesaw (ISS) neutrinos and singly charged Higgs bosons, which accommodate all the data of neutrino oscillation, the (g-2)_{e_a} anomalies of muon and electron, and the lepton flavor violating (LFV) decays. We will show that one-loop contribution related to ISS neutrino exchanges can lead to large LFV decay rates...

Prof. Pyungwon Ko (KIAS (Korea Institute for Advanced Study))12/12/24, 5:20โฏPMInvited Talk
During the last few decades, many experimental anomalies were reported and then most of them eventually disappeared. Very often they employ simplified or phenomenological models in order to interpret anomalous data. I will show a few examples where this common approach largely fails, and emphasize that it is important to interpret the anomalous data in mathematically consistent models.

Prof. Shao-Feng Ge (TDLI-SJTU)12/13/24, 9:30โฏAMInvited Talk
The cosmic gravitational focusing (CGF) is the 3rd cosmological way of measuring the neutrino masses. Different from the existing methods with CMB and large scale structure that have linear dependence on the neutrino mass sum, CGF is sensitive to the fourth power of the neutrino masses and hence can provide an independent measurement of the neutrino mass. We thoroughly explore the cosmic...

False vacuum decay plays an important role in many branches of physics. In many systems, the initial state is in local thermodynamic equilibrium around the metastable minimum. For such systems the Euclidean path integral is a powerful tool to compute the decay rate or the shape of the true vacuum bubble. On the other hand, the Euclidean approach does not capture real-time dynamics of the phase...

Mark Hertzberg (Tufts University)12/13/24, 11:00โฏAM
The prospect of detecting/constraining deviations from general relativity by studying gravitational waves (GWs) from merging black holes has been one of the primary motivations of GW interferometers like LIGO/Virgo. Within pure gravity, the only possible way deviations can arise is from the existence of higher order derivative corrections, namely higher powers of the Riemann curvature tensor,...
