Results from the Facility for Rare Isotope Beams (FRIB) reveal the first microsecond isomer for exotic N=20 nuclei. Implications for nuclear structure and the competition between spherical and deformed shapes will be discussed.
Transverse force tomography is a relatively new technique that offers an alternative perspective on confining forces in Quantum Chromodynamics. We present the first lattice QCD computation of the spatial distribution of the "Colour-Lorentz" forces in the proton.
Shell effects in nuclear fission of superheavy oganesson-294 are investigated through simulations of quasifission trajectories. Results show that shell effects from fission affect quasifission along with excitation energy dependent changes.
This presentation addresses the design and implementation of the pyrate software system developed within the context of the SABRE experiment for dark matter direct detection. The system is oriented at processing and analysing the data collected by the experiment.
Long Lived Particles are predicted in many BSM models. This is an overview of previous analyses to highlight where missing energy, with additional data may be more sensitive to SUSY signals, or to help set limits on supersymmetric particle masses.
We report on recent advances in reconstructing the internal quark and gluon structure of the nucleon through global QCD analysis of high energy scattering data.
The beauty and charm quarks are ideal probes of perturbative Quantum Chromodynamics, owing to their large masses. The formation of hadrons from quarks produced in different parton-parton interactions within the same proton-proton collision is studied using doubly-heavy hadrons.
By performing a combined analysis of data from pion-Nucleon scattering experiments with first-principles calculations from lattice QCD, we gain insight into the composition and structure of the low-lying odd-parity Nucleon resonances.
I focus on the QCDSF/UKQCD/CSSM lattice collaboration's advances in calculating the forward Compton amplitude of nucleon via an implementation of the second-order Feynman-Hellmann theorem. I highlight our progress on investigating the low moments of (un)polarised structure functions of the nucleon.
Pertaining to the analysis of heavy vector production at the LHC, this project focuses on vector boson fusion as the dominant production channel for heavy vector triplets and presents limits within the relevant parameter space.
We report on a recent determination of the weak charge of the proton in parity-violating electron–proton scattering. The result is in excellent agreement with the standard model prediction, providing bounds on new physics interactions at the multi-TeV mass scale.
We highlight the potential uncertainties that may arise from the nuclear components of WIMP-nucleus scattering amplitudes, due to nuclear structure theory within the framework of the nuclear shell model.
The quark-gluon vertex is an important ingredients of one of the strong interaction. It is an essential ingredient in functional approaches to nonperturbative quantum chromodynamics. We will summarise the latest developments in quark-gluon vertex and its implications in hadron physics.
We investigate employing quantum machine learning algorithms for B meson flavour tagging, an important component of the experiments at Belle-II which study heavy quark mixing, CP violation and the matter-antimatter asymmetry of the universe.
This presentation describes an experimental study of the highest-multipole transition known in nature$-$the proposed E6 $\gamma$-decay of $^{53m}$Fe$-$ and attempts to understand this rare process through Shell Model calculations performed in the full fp-shell model space.
Finite-volume pionless effective field theory is an efficient framework with which to perform the extrapolation of finite-volume lattice QCD calculations of multi-nucleon spectra and matrix elements to infinite volume and to nuclei with larger atomic number. Recent progress is reviewed.
I give an update on the Global And Modular BSM Inference Tool and show the latest results for a model where the gravitino and the lightest neutralinos and charginos are the only light sparticles in the Minimal Supersymmetric Standard Model.
Where does your mass come from? The Higgs mechanism only accounts for 1% of the proton mass. We reveal how centre vortices connect emergent phenomena such as quark confinement and dynamical mass generation with the QCD vacuum state.
We present studies of the $\Delta$ baryon spectrum using lattice QCD and Hamiltonian Effective Field Theory. Our results suggest quark model-like states and meson-baryon two-particle states both contribute to the energy spectrum observed in experiment.
We report branching fraction and $CP$ asymmetry measurements of the $B^{0}\to\pi^{0}\pi^{0}$ decay mode at Belle II using a data sample corresponding to $198\times10^{6} B\bar{B}$ pairs. This is comparable sensitivity with 1/4th of the Belle dataset.
I will show the sorts of physics model that are currently evading detection at the Large Hadron Collider, and will present new ideas for how to extend the reach of particle searches with the ATLAS and CMS detectors.
We review various methods used to estimate uncertainties in parton distribution functions (PDFs), finding that utilizing a neural network on a simplified example of PDF data has the potential to inflate uncertainties.
This work examines the sensitivity of the upcoming SABRE South experiment to the annual modulation dark matter signal. We also consider the effect of a hemisphere-dependent seasonal background on direct detection experiments.
This presentation will discuss preliminary attempts to perform Coulomb excitation of $^{124}$Te with the CAESAR array at the ANU as part of a larger investigation into the vibrational nature of near-spherical nuclei.
Fixed Field Accelerators offer potential advantages for particle therapy, however many challenges remain. We address the problem of resonance crossing during acceleration, showing that beam stability can be maintained by fixing the normalised focusing strength.
The SABRE-South experiment, located at SUPL, Australia, aims to detect dark matter to provide a model independent test of the signal observed by DAMA/LIBRA.
This talk will describe the complexity of SABRE-South and the general status of its assembly.
This contribution will summarise results from the ATLAS Experiment at the CERN Large Hadron Collider related to the Higgs boson, top quarks and various searches for the beyond the Standard Model phenomena.
The nature of dark matter is still unknown and it is one of the key questions in particle physics. Many beyond the Standard Model theories predict the production of dark matter particles in the decays of the Higgs boson. As dark matter particles do not interact with the detector, they would be invisible to the detector and can only be probed using the presence of missing transverse...
We propose a variant-axion extension of the Standard Model (coined VISHν) which additionally explains small neutrino masses, dark matter, the baryon asymmetry of the universe and inflation, while remaining technically natural and cosmologically benign.
Possible new physics is incorporated into the QMC energy density is shown to be capable of predicting a neutron star mass of 2.1 M$_\odot$ without changing the symmetric nuclear matter properties at saturation density.

We propose that parity-violating electron scattering (PVES) provides promising opportunity for the dark photon searches. We explore the sensitivity of PVES asymmetry to the dark photon parameters. We also extract the favoured region by fitting the parity-violation data.
We present the current status and future plans of the experiments within The Oscillating Resonant Group AxioN (ORGAN) Collaboration, which develops axion haloscopes. Axions are a compelling dark matter candidate, and haloscopes are a tool for axion searches.
We will summarise current searches within Belle II to identify the rare, leptonic B- decays B+ → μ+ν or B0 → νν ̄ and detail how the upper bounds on experimental branching fractions of these rare decays will be improved.
A measurement of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element $|V_{\mathrm{ub}}|$ is extracted exclusively from the semileptonic $B$-meson decay $B \to \pi \ell \nu$ in an early subset of Belle II data using hadronic Full-event-interpretation tagging.
This talk will present the characterisation methods and results of intrinsic backgrounds in an ultra-pure NaI crystal for the SABRE South dark matter experiment, with a focus on 238U and 232Th.
E0 transitions are unique to nuclei and provide a compelling spectroscopic fingerprint of shape coexistence. Recent results from 12C, 24Mg and 40Ca will be used to examine nuclear structure questions where the observation and characterisation of E0 transitions were crucial.
Using modern visualisation techniques, this presentation examines the structure of centre vortices in the nontrivial ground-state fields of QCD. Their link to the generation of mass and the confinement of quarks is explored.
A presentation of our recent work to determine the 3D structure of hadrons using lattice quantum chromodynamics. This work complements forthcoming experiments at the Brookhaven Electron-Ion Collider.
WIMPs are a strongly motivated dark matter candidate, expected to produce measurable nuclear recoils, while background events produce electron recoils. Classification of recoil events is important for improved detection of dark matter. PSD approaches are developed to improve event classification.
EMC Effect is the 40-year-old mystery that quark structure in free nucleons is somehow different to that in bound nucleons. We examine its two leading explanations - mean field correction and short-range correlation.
