Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.
At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper investigates the numerical challenges and convergence properties of self-interacting dark matter (SIDM) N-body simulations during the gravothermal collapse phase, demonstrating that high-resolution simulations with strict energy conservation can accurately model the formation of compact halos capable of explaining observations like the GD-1 stellar stream.
This paper presents a global fit of electroweak precision observables for dark photon models featuring both kinetic and mass mixing arising from an extended scalar sector, revealing that while moderate scalar vacuum expectation value ratios exclude dark photon masses between 40 GeV and 1 TeV, ample unconstrained parameter space remains for larger ratios.
This study analyzes the causal constraints of the Mueller-Israel-Stewart theory for heat flow in heavy-ion collisions, revealing that realistic conditions lead to causality-violating heat fluxes that suggest either an overestimation of transport coefficients or a breakdown of the fluid approximation.
This paper demonstrates that modified loop quantum cosmology (mLQC-I) naturally drives the Bianchi I universe toward isotropy by dynamically suppressing cosmological shear through a robust quantum-gravitational mechanism after the bounce, independent of the matter equation of state.
This paper extends the framework of caustic-crossing microlensing to include extended dark matter objects, demonstrating that such objects can generate distinct light curve features and allowing for constraints on ultracompact minihalos up to using the MACS J1149 LS1 event, thereby complementing galactic microlensing searches with sensitivity to larger physical scales.
This paper presents a detailed analysis of proton electromagnetic form factors using exclusive photon leptoproduction data in the Beth-Heitler dominant region, demonstrating that such measurements can provide complementary constraints on the Dirac form factor and yield a charge radius consistent with recent high-precision PRad results.
This paper demonstrates that charged spinless vortex particles accelerated in linear accelerators retain their orbital angular momentum with negligible losses due to photon emission, proving that their quantum states are robust enough to reach relativistic energies in both conventional and wake-field accelerators.
This paper systematically investigates the twist structure and mass dependence of ground-state pseudoscalar and vector quarkonium light-cone distribution amplitudes within the light-front quark model, revealing that increasing quark mass drives the amplitudes toward a universal, twist-independent, and nonrelativistic limit characterized by vanishing odd moments and a progressively narrower, more compact momentum distribution.
By analyzing data from multiple experiments including Atomki, KLOE-2, and PADME, the authors conclude that no viable parameter space exists for the particle across various coupling models, suggesting the Atomki anomaly likely stems from an unexplained nuclear effect rather than new physics.
This paper investigates three late-time gravity models using DESI BAO and other cosmological data to determine if torsional modifications can alleviate the tension, finding that while phantom-like regimes can partially shift the Hubble constant toward local measurements, none of the models are statistically preferred over the standard CDM model.
