Summary: This study investigates the mass spectra of N Omega dibaryons in different channels and predicts the existence of a bound state in the S-5(2) channel. The results suggest that N Omega dibaryons in the S-3(1) channel may decay directly into final states in S wave. This research provides insights into the potential identification of these N Omega dibaryons in future relativistic heavy-ion collision experiments.

Summary: This article discusses the implications of permutation symmetry on the state space and dynamics of quantum mechanical systems of matrices of general size N, solving a corresponding Hamiltonian and calculating partition function. It describes how the permutation invariant sector of the Hilbert space can be represented using partition algebra diagrams, with the integer k interpreted as the degree of matrix oscillator polynomials. Families of interacting Hamiltonians diagonalized by a representation theoretic basis for the permutation invariant subspace are also explored.

Summary: In this study, the magnetic moments of possible T++cc states were calculated using light-cone sum rules. The results reveal that the T++cc states have large magnetic moments due to their double electric charge. Measurement of the magnetic moment of these states can provide valuable information about their substructure and quantum numbers.

Summary: We generalize Luscher's lattice topological charge to the case of 4d SU(N) gauge fields coupled with DOUBLE-STRUCK CAPITAL Z(N) 2-form gauge fields, while maintaining locality, SU(N) gauge invariance, and DOUBLE-STRUCK CAPITAL Z(N) 1-form gauge invariance. The central role in our construction is played by the manifest 1-form gauge invariance. This result provides a lattice regularized derivation of the mixed 't Hooft anomaly in pure SU(N) Yang-Mills theory between its DOUBLE-STRUCK CAPITAL Z(N) 1-form symmetry and the & theta; periodicity.

Summary: It is generally believed that a 1+1D model for a single chiral fermion cannot exist alone on a lattice. The main obstacle is the inability to reproduce the quantum anomalies of a chiral fermion in the continuum. This paper proposes a 1+1D chiral fermion model on a 1D spatial lattice, which stands independently without being associated with a 2D bulk, by using a simple non-Hermitian hopping Hamiltonian. It is demonstrated that the model exhibits the same chiral anomaly and gravitational anomaly as the continuum theory.

Summary: In this study, a QCD sum rules analysis is performed on the Xi(Q) - Xi(Q)' mixing. It is found that only dimension-4 and dimension-5 operators contribute to the mixing, indicating its non-perturbative nature. The mixing angle is predicted to be (1.2 to 2.8) degrees for the Q = c case and (0.28 to 0.34) degrees for the Q = b case. The small mixing angle is unlikely to resolve the tension between recent experimental measurement and lattice QCD calculation for the semileptonic decay Xi(0)(c) -> Xi(-)e(+)nu(e).

Summary: Motivated by the recent discovery of the exotic state Z(cs) (3985) by the BESIII Collaboration, this study explores the possible interpretation of this state at different temperatures. The mass and meson-current coupling constant of the resonance are analytically computed, considering non-perturbative contributions and up to sixth order of the thermal operator dimension. The modifications on the Z(cs) (3985) properties in a hot medium are determined by extracting thermal mass and meson-current coupling constant sum rules. Additionally, the hadronic parameters of the bottom partner of Z(cs) (3985) are estimated. The research sheds light on phase transitions, chiral symmetry breaking, and the properties of hot-dense matter in QCD.

Summary: This study examines the phenomenon of charge teleportation between two spatially separated objects without exchanging charged particles, which is achieved through anomaly inflow and implies the presence of anomalous quantum mechanics. Despite charge violation in the anomalous theories living on these objects, the total charge between the two spatially separated objects remains conserved.

Summary: The collision of heavy ions produces strong magnetic and electric fields that significantly influence the evolution of quark-gluon plasma (QGP). Understanding these fields is crucial for studying the role of topological fluctuations in the QGP through the chiral magnetic effect. Through our work, we found that electromagnetically induced currents result in charge-odd directed flows and that while the predicted magnitude agrees with data, the sign of the predicted asymmetry between flows of positive and negative hadrons differs from actual observations.

Summary: The BEST Collaboration was formed to provide a theoretical framework for analyzing data from the Beam Energy Scan program at RHIC, with the goal of searching for a QCD critical point and manifestations of the chiral magnetic effect. Progress has been made in studying the equation of state, initial state models, hydrodynamic framework, freezeout prescriptions, and hadronic transport models over the past five years, with the challenge of integrating these components into a complete analysis framework.

Summary: Our paper explores the Chiral Magnetic Josephson junction (CMJ junction) composed of two non-centrosymmetric superconductors connected by a uniaxial ferromagnet. This structure shows an analog of the Chiral Magnetic Effect and has potential applications as a qubit with a tunable Hamiltonian. The CMJ junction offers a simpler and more robust architecture without the need for an offset magnetic flux, providing strong protection against noise from magnetization fluctuations.

Summary: The paper investigates the anomalous transport driven by a combination of shear, vorticity, and magnetic field. It finds characteristic charge correlations among the hadrons produced in heavy ion collisions. The proposed charge asymmetry of triangular flow is suggested as a signature of the anomalous transport, and the strength of the signal as well as the background is estimated using hydrodynamical model simulations. The signal-to-background ratio for the proposed observable is found to be favorable for experimental detection.

Summary: In quantum electrodynamics with charged fermions, a background electric field leads to the chiral anomaly, creating a chirally imbalanced state of fermions through entangled pairs production. The statistical Gibbs entropy associated with these pairs is found to be equal to the entropy of entanglement between right-moving particles and left-moving antiparticles. It is observed that short pulses, such as those from high energy collisions, result in an approximately thermal distribution for the produced particles.

Summary: The mass radius of the proton was determined using the form factor of the trace of the energy-momentum tensor of QCD, with a resulting value of Rm = 0.55 +/- 0.03 fm. This value was found to be significantly smaller than the charge radius of the proton, with the difference attributed to the effects of asymptotic freedom and spontaneous breaking of chiral symmetry in QCD. Future measurements are needed to further refine the determination of the mass radius.

Summary: The text discusses how to define parton distributions based on the entanglement entropy between the probed region in deep inelastic scattering and the rest of the proton. It argues that a more accurate account of the number of color-singlet dipoles in the H1 experiment can be given by the sea quark structure function and 1/N corrections. By taking these modifications into account, the data from the H1 collaboration align well with the prediction based on entanglement.

Summary: A general kinetic theory of anomalous transport in Weyl systems was constructed using phase space Berry curvature induced by torsion, which describes the generation of chiral chemical potential and the chiral magnetic effect in the presence of a background magnetic field. Researchers proposed to measure the CME current induced by torsion as a way to detect the anomalous coupling between the coordinate-space and momentum-space chiralities.

Summary: In this study, the coupling between the spin of a massive Dirac fermion and the angular momentum of the medium, known as the gravitomagnetic moment, is shown to be renormalized by QED interactions at finite temperature. The anomaly gravitomagnetic moment (AGM) is found not to vanish, and it suggests that thermal effects can disrupt the Einstein equivalence principle in quantum field theory. Additionally, the AGM contributes to radiative corrections in the axial current of massive fermions induced by vorticity in quantum relativistic fluids, with potential significant impacts on the production of polarized hadrons in heavy-ion collisions due to radiative QCD effects.

Summary: The study shows that in the (1 + 1)-dimensional massive Schwinger model with a theta-term, a sharp maximum in the topological susceptibility is observed near the parity-breaking critical point where theta = pi and the fermion mass to coupling ratio is approximately 0.33. This phenomenon is interpreted as being related to the growth of critical fluctuations near the critical point, and analogies are drawn between the massive Schwinger model, QCD near the critical point, and ferroelectrics near the Curie point.
