Efficient Hamiltonian Truncation: Fast Matrix Construction and Quantum Krylov Diagonalization

This paper presents a hybrid classical-quantum strategy to enhance the efficiency of Hamiltonian truncation for quantum field theories by introducing an integer partition-based basis generation, symmetry-aware sparse matrix construction, and quantum Krylov diagonalization, demonstrating significant computational gains in two-dimensional scalar and ϕ4\phi^4 models.

Beyond Δm2\Delta m^2: Absolute Mass Sensitivity in Neutrino Oscillations

This paper demonstrates that neutrino oscillations can probe the absolute neutrino mass scale through next-to-leading-order corrections in the oscillation phase, revealing that the JUNO experiment could detect masses of a few hundred keV, thereby offering a novel and complementary method to existing mass constraints.

Bayesian inference of event-by-event collision geometry from charged-particle multiplicity in heavy-ion collisions

This paper introduces the Inference-driven Participant Determination (IPD) method, a Bayesian framework that utilizes charged-particle multiplicity and Monte-Carlo Glauber priors to probabilistically infer event-by-event collision geometry, thereby reducing volume fluctuations and improving the reconstruction of net-proton cumulants compared to conventional centrality classification.

Exploring the chiral magnetic effect in Au+Au collisions at sNN=7.7−200\sqrt{s_{NN}}=7.7-200 GeV through Chiral Anomaly Transport

Using a Chiral Anomaly Transport module within the AMPT model, this study identifies a significant Chiral Magnetic Effect signal in Au+Au collisions at sNN=11.5−27\sqrt{s_{NN}} = 11.5-27 GeV that aligns with STAR data, while finding the signal vanishes at 7.7 and 200 GeV due to the energy-dependent dynamics of the magnetic field and chemical freeze-out time.

Probing the Single Production of First-Generation Singlet Vector-like Leptons at Future e+e−e^+e^- Colliders

This paper demonstrates that future e+e−e^+e^- colliders, specifically the 1 TeV ILC and 1.5 TeV CLIC, can effectively probe first-generation singlet vector-like leptons via single production channels with boosted decay signatures, achieving mass discovery reaches up to 900 GeV and 1400 GeV respectively, which surpass current hadron collider limits.

Simultaneous production of a WW boson and a charmed hadron at the LHC in general-mass variable-flavour-number scheme

This paper investigates the simultaneous production of WW bosons and charmed hadrons at the LHC using next-to-leading order QCD calculations in a general-mass variable-flavor-number scheme, finding that while ratio observables effectively reduce theoretical uncertainties and reveal tension between ATLAS data and PDF sets allowing non-zero strangeness asymmetry, the processes show limited sensitivity to intrinsic charm and nuclear PDFs.
