A Novel Quantum Realization of Jet Clustering in High-Energy Physics Experiments
Exploring the application of quantum technologies to fundamental sciences holds the key to fostering innovation for both sides. In high-energy particle collisions, quarks and gluons are produced and immediately form collimated particle sprays known as jets. Accurate jet clustering is crucial as it retains the information of the originating quark or gluon and forms the basis for studying properties of the Higgs boson, which underlies teh mechanism of mass generation for subatomic particles.

Good article summarizing a lot of things relevant to continued COVID'19 caution:
https://www.cbc.ca/radio/quirks/beyond-long-covid-1.7485888
Key points:
COVID'19 weakens the immune system:
"""
So it's not just about infecting you and causing respiratory illness and fever and all of the things that we usually get with the viral infection. This virus also specifically causes your immune system to become weaker.
"""
It damages blood vessels:
"""
In addition to SARS-CoV-2's ability to dysregulate the immune system and suppress the immune system, the spike protein itself is very damaging to blood vessel structures as well as red blood cells and platelets themselves.
"""
The folk idea that infections make our immune system stronger and stronger like a muscle just isn't true (or at least, doesn't apply to COVID'19 because of how, unlike most other viruses, it damages the immune system):
"""
For the longest time in the field of immunology, there was the sort of adage that your immune system needs to be tested every now and again to stay strong. That's an old-fashioned idea.
The more new-fashioned and evidence-based idea is that, although your immune system can take on [a COVID] infection, you want to avoid testing it as much as possible because your body is sustaining damage with each infection that it survives.

Physics-Informed Neural Network Approach to Quark-Antiquark Color Flux Tube
We introduce a physics-informed neural network (PINNs) framework for modelling the spatial distribution of chromodynamic fields induced by quark-antiquark pairs, based on lattice Monte Carlo simulations. In contrast to conventional neural networks, PINNs incorporate physical laws--expressed here as differential equations governing type-II superconductivity--directly into the training objective. By embedding these equations into the loss function, we guide the network to learn physically consist…

LLMs are starving for knowledge graphs. Raphael Troncy was pointing out that many LLM company crawlers are constantly visiting their KGs. Some crawlers even perform explicit SPARQL queries on the KGs.

Role of thermal fluctuations in nucleation of three-flavor quark matter
We present a framework that aims to investigate the role of thermal fluctuations of the matter composition and color-superconductivity in the nucleation of three-flavor deconfined quark matter in the typical conditions of high-energy astrophysical systems related to compact stars. It is usually assumed that the flavor composition is locally fixed during the formation of the first seed of deconfined quark matter since weak interaction acts too slowly to re-equilibrate flavors. However, the matte…

Modular domain walls and gravitational waves
We discuss modular domain walls and gravitational waves in a class of supersymmetric models where quark and lepton flavour symmetry emerges from modular symmetry. In such models a single modulus field $τ$ is often assumed to be stabilised at or near certain fixed point values such as $τ= {\rm i}$ and $τ= ω$ (the cube root of unity), in its fundamental domain. We show that, in the global supersymmetry limit of certain classes of potentials, the vacua at these fixed points may be degenerate, …

Charge Separation Measurements in Au+Au collisions at $\sqrt{s_{NN}}=$ 7.7--200 GeV in Search of the Chiral Magnetic Effect
The chiral magnetic effect in heavy-ion collisions predicts a charge separation signal along a magnetic field, which indicates local $P$ and $CP$ violations in the quark-gluon plasma. We report measurements of electric charge separation signals perpendicular to the spectator event plane in Au+Au collisions using high-statistics data from RHIC Beam Energy Scan II and top-energy runs. A novel event shape selection method is employed to suppress the flow-induced background. The residual charge sep…

Confining Quantum Chromodynamics Model for 3-Quark Baryons, New Mass Source, `Proton Spin Crisis' Solution and Idealized Quark-Lepton Mass Symmetry
We discuss a model for the relativistic bound states of 3-quark baryons based on confining quantum chromoynamics (QCD) with general Yang-Mills symmetry. The model postulates that 3-quark states are formed by consecutive 2-body collisions. For a proton, d and u quarks get together first, and then they capture another u quark so that the d quark is at the core to form a stable proton state with intergral electric charge. The two u quarks form a quantum spheric shell and move in a confining potent…

$η_cη_c$ and $J/ψJ/ψ$ scatterings from lattice QCD
We investigate the $J^{PC}=(0,2)^{++}$ $η_c η_c$ and $J/ψJ/ψ$ scatterings in $N_f=2$ lattice QCD at two pion masses $m_π\approx 420$\,MeV and 250\,MeV. The quark field smearing scheme used in the distillation method strongly suppresses high-momentum states, thereby limiting the maximum accessible center-of-mass energy in this study to approximately 6.6\,GeV. Given the observed near-decoupling of the $η_cη_c$ and $J/ψJ/ψ$ channels, we analyze their scattering properties using the single…
