Recent progress in hadron-hadron interactions with lattice QCD simulations close to the physical pion mass opens the door for quantitative studies of the poorly understood low-energy hadron interactions with charm and strange quarks. It also allows comparison with femtoscopic studies in pp, pA, and AA collisions at RHIC (Relativistic Heavy Ion Collider at BNL) and LHC (Large Hadron Collider...
The quark model was formulated in 1964 to classify mesons as bound states made of a quarkโantiquark pair, and baryons as bound states made of three quarks. However, in principle QCD also allows the existence of more complex structures, generically called exotic hadrons or known as XYZ states. These include fourquark hadrons (tetraquarks and hadronic molecules), five-quark hadrons (pentaquarks)...
After discussing the landscape of strongly interacting field theories, I will introduce novel theoretical approaches aimed at solving their complex dynamics. Following this, I will explore applications to particle and astroparticle physics, including the discovery of new strong dynamics via gravitational wave observatories. In the realm of particle physics, I will provide a mathematical...
The phase structure of QCD remains an open fundamental problem of standard model physics. In particular at finite density, where importance sampling based methods like lattice QCD are severely restricted, our knowledge is limited. Yet, numerous model studies point towards a rich and complex phase diagram at large density. In addition to their fundamental relevance, the thermodynamic and...
While the mandate of particle physics research institutes is fundamental research, the developed technologies find applications for the benefit of society. With the aim to highlight their impact on medical applications and in particular on cancer treatment, the new Particle Therapy MasterClass (PTMC) package was developed and integrated into the International MasterClass 2021 (IMC) online...
The ARC Centre of Excellence for Dark Matter Particle Physics has developed a partner school program to build long-term collaborations with traditionally underserved regional and rural schools in Australia. Now in its fourth year, this program has expanded to seven schools across two states.
In this session, we will discuss: The inspiration, drive, and support behind the development of the...
There have been rapid developments in the direct calculation in lattice QCD (LQCD) of the Bjorken-x dependence of hadron structure through large-momentum effective theory (LaMET) and other similar effective approaches. These methods overcome the previous limitation of LQCD to moments (that is, integrals over Bjorken-x) of hadron structure, allowing LQCD to directly provide the kinematic...
In high energy collision experiments with multiple hadron productions, the momentum distribution of the measured hadron pair shows a correlation due to the hadron interactions and the quantum statistics. In the past, this femtoscopy technique has been developed to extract the information of the emission source from the momentum correlation functions. Recently, correlation function measurement...
In this talk I review our current understanding of the interior of neutron stars and modern constraints relevant for dense matter. This includes theoretical first-principle results from lattice and
perturbative QCD, as well as chiral effective field theory results. From the experimental side, it includes heavy-ion collision and low-energy nuclear physics results, as well as observations from...
After briefly reviewing the axion solution to the strong CP problem, I will discuss recent new alternative ideas based on CP as part of a spontaneously broken flavour symmetry such as modular invariance.
Beta decays offer an opportunity for low-energy precision tests of the Standard Model, in particular, checking the unitarity of the first-row CKM matrix which connects the weak and QCD flavor bases. These tests require a combination of the experimental measurements, effective field theory and phenomenology, as well as lattice QCD for non-perturbative input. State of the art theory...
Almost twenty years ago, physicists at at Brookhaven National Laboratory measured the magnetic moment of the muon with a remarkable precision of 0.54 parts per million. Since that time, the reference Standard Model prediction for this quantity has exhibited a persistent discrepancy with experiment of more than three sigma. This raises the tantalizing possibility of undiscovered forces or...
Whether interested in hadron spectroscopy, nuclear structure, or precision tests of the standard model, three-hadron dynamics play a key role in a broad class of rich physical phenomena. Presently, lattice QCD is the only non-perturbative tool for studying QCD exactly. In this talk, I review novel formal techniques that have allowed to non-perturbatively constraining scattering amplitudes...
Relativistic heavy-ion collisions at the LHC create the quarkโgluon plasma (QGP); a state of matter where quarks and gluons are not confined inside hadrons. In this review talk I will show what measurements of key observables in Pb-Pb, Xe-Xe, p-Pb and pp collisions at the LHC experiments have taught us about the hottest fluid ever studied in the laboratory and what this tells us about the...
Sasha Andrianov passed away a few months ago. His work span more than four decades in high energy physics, with very significan contributions associated to current trends in the theory of elementary particles: bosonization of quantum chromodynamics, Higgs physics, cosmology of complex systems, supersymmetric quantum mechanics, anomalies in quantum field theory, local parity violation under...
Since the discovery of the complex potential of quarkonium at high temperatures, quarkonium has been regarded as an open quantum system within the quark-gluon plasma. Recently, a similar issue regarding in-medium bound states of impurities has also emerged in particle physics and cold atomic physics. In this talk, I will provide an overview of recent advancements in understanding key...
The bulk of visible mass emerges from nonperturbative dynamics within quantum chromodynamics (QCD) - the strong interaction sector of the Standard Model. Following many years of development and refinement, continuum and lattice Schwinger function methods have recently joined in revealing the three pillars that support this emergent hadron mass (EHM); namely, a nonzero gluon mass-scale, a...
Statistical methods play a crucial role in the data analysis and interpretation in particle physics experiments. As we deepen in the theory and build more complex experiments, new challenges arise in statistical practice. In this talk, we explore some of the open questions, new and old, and ongoing debates in statistical methodology as applied to particle physics research.
Hypothesis testing...
I will present an overview of recent lattice QCD results on the equation of state and phase diagram of strongly interacting matter, complemented by phenomenological extensions to high density and low temperature, to connect the heavy-ion and neutron star merger regimes.
Heavy quarks may be produced in the earliest stage of ultra-relativistic heavy-ion collisions, and may or may not bind into quarkonia. They probe the full evolution of the strongly-coupled medium created in these collisions.
In-medium quarkonia are subject to a dynamical melting process, which can be understood in terms of the static potential. EFT calculations predict a complex potential,...
The connection between power corrections to perturbative series and the factorial growth of the series coefficients is studied, leading to a more convergent packaging of perturbation theory. Results for quark masses and preliminary results for $\alpha_s$ are presented.
This is a personal account of some of the progress made in heavy quarkonium physics in the last 30 years from the perspective of non relativistic effective field theories.
