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.

Precise theoretical prediction on branching fractions and polarizations of DVVD \to V V decays

This paper presents a precise theoretical analysis of DVVD \to VV decays using the factorization-assisted topological-amplitude (FAT) approach, where 10 nonfactorizable parameters are globally fitted to 36 experimental data points to reveal that large strong phases in the EE amplitude cause destructive interference with the CC component, leading to a polarization hierarchy (f>fLf_\parallel > f_L) that contradicts naive factorization predictions.

Supermassive black hole formation in the initial collapse of axion dark matter

This paper proposes that the rethermalization of axion dark matter during the initial collapse of large-scale overdensities near cosmic dawn efficiently transports angular momentum outward, leading to the formation of supermassive black holes with masses ranging from 10510^5 to a few times 1010 M10^{10}~M_\odot for both QCD axions and heavier axion-like particles.

Observation of a dynamic magneto-chiral instability in photoexcited tellurium

Using time-domain terahertz emission spectroscopy, researchers observed a dynamic magneto-chiral instability in photoexcited tellurium, where an electric current parallel to a magnetic field amplifies electromagnetic waves, offering a promising mechanism for THz-wave amplification in chiral materials.
