The Scalar MSW Effect: Compact analytical formulas for neutrino oscillations with large matter effects, including μ−μ\mu -\mu and τ−τ\tau -\tau dominant matter potentials

This paper extends the Jacobi diagonalization method to derive compact, accurate analytical formulas for three-flavor neutrino oscillations in matter, revealing that scalar non-standard interactions can induce an energy-independent resonant "scalar MSW" effect and providing effective parameter mappings for both standard and exotic matter potentials.

Drell-Yan lepton pair production from low to high transverse momentum

This paper presents a comprehensive technique for computing Drell-Yan lepton pair production across a wide transverse momentum range with unprecedented theoretical precision, incorporating non-perturbative lattice QCD inputs and utilizing a maximum entropy approach to generate strictly positive event weights.

Clash of the Titans: ultra-high energy KM3NeT event versus IceCube data

This paper reports a significant statistical tension (2.0σ–3.6σ) between KM3NeT's detection of a single ultra-high-energy neutrino event exceeding 10 PeV and the absence of similar events in IceCube's longer dataset, suggesting the KM3NeT observation likely represents the first detection of a new, distinct astrophysical source rather than a standard diffuse flux.

On the phenomenological implications of a Pati-Salam model spontaneously broken by Higgs fields in fundamental representations

This paper proposes a supersymmetric Pati-Salam model utilizing small fundamental and bi-doublet Higgs representations, augmented by discrete symmetries and neutral singlets, which successfully addresses domain wall issues, achieves near-conformal behavior for the SU(4)CSU(4)_C coupling, suppresses proton decay, and disentangles quark and lepton masses via higher-dimensional operators, thereby offering a string-theory-friendly alternative to traditional GUTs.

Modeling Uncertainties on the Z Boson Background in the Context of High Precision W Boson Mass Measurements

This study investigates the impact of ZZ boson background modeling uncertainties on high-precision WW boson mass measurements in the muon decay channel, finding that while such mismodeling can induce a non-negligible 8 MeV shift, it is insufficient to explain the significant discrepancy observed in the CDF collaboration's results.

Modular TM1_1 mixing in light of precision measurement in JUNO

This paper investigates modular S4S_4 symmetry models predicting the TM1_1 lepton mixing pattern, utilizing JUNO's precision measurements to constrain their parameter spaces and demonstrate how distinct model-building strategies lead to different, distinguishable predictions for the lightest neutrino mass and the effective Majorana mass in neutrinoless double beta decay.

POPxf: An Exchange Format for Polynomial Observable Predictions

The paper introduces POPxf, a structured, machine-readable data format designed to encode semi-analytical theoretical predictions as polynomials in model parameters—particularly for Effective Field Theory applications—to enhance reproducibility, facilitate global fits, and streamline the exchange of uncertainty-aware results within the high-energy physics community.

Possible solution to the gallium anomaly moving beyond the leptonic wave function factorization

This paper proposes that the long-standing gallium anomaly—a significant deficit in neutrino capture rates on 71^{71}Ga—may be resolved by revising the theoretical cross-section calculation to move beyond standard leptonic wave function factorization and instead incorporate phenomenologically constrained Gamow-Teller transition densities that correctly reproduce the 71^{71}Ge half-life, thereby eliminating the need for new physics explanations.
