hep-ph papers | Gist.Science

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.

Fixed points of the renormalisation group running of quark and fermion mixing matrices in the Standard Model and beyond

This article investigates the renormalization group running of fermion mixing matrices within and beyond the Standard Model, identifies specific fixed points at one-loop order whose geometric properties are argued to persist to all orders, and simultaneously establishes the existence of at least $N_g!$ such fixed points when $N_g$ dark or sterile neutrinos are included.

Hadronic tau decays at higher orders in QCD

This paper employs nonlinear sequence-transformation techniques, specifically the Shanks transformation and Wynn's $\varepsilon$ -algorithm, to estimate higher-order perturbative coefficients and predict the QCD correction for hadronic $\tau$ decays, offering an efficient alternative to explicit multi-loop calculations.

Tensor form factors of decuplet hyperons in QCD

This work investigates the tensor form factors and quark tensor charges of the hyperons $\Omega^-$ , $\Sigma^{*+}$ , and $\Xi^{*-}$ within the framework of QCD sum rules and provides new non-perturbative insights into the spin structure of spin-3/2 baryons for future phenomenological and experimental studies.

Searching for a $P_{cs}(4200)$ state in the $\Lambda_b\to\phi\eta_c\Lambda$ reaction

This paper proposes the $\Lambda_b\to\phi\eta_c\Lambda$ reaction as a viable method for the LHCb collaboration to observe a predicted $P_{cs}(4200)$ state with a narrow width of approximately 200 keV, thereby shedding light on the role of coupled channels in the structure of hidden-charm pentaquarks.

Metastable strings at PTAs: classical stability analysis

This paper investigates the classical stability of metastable strings arising from an $SU(2) \to U(1) \to 1$ symmetry breaking chain, identifying parameter regions where such instabilities significantly impact the viability of these strings as candidates for the gravitational wave background detected by Pulsar Timing Arrays.

Searching for UFOs from the early universe: direct detection prospects for relativistically decoupling dark matter

This paper demonstrates that ultrarelativistically frozen-out (UFO) dark matter candidates, particularly those mediated by a $Z'$ portal, represent a viable and detectable alternative to traditional WIMPs, with current experiments like LZ and XENONnT already constraining their parameter space and future detectors such as SuperCDMS SNOLAB poised to explore significant regions in the 0.5–10 GeV mass range.

Closing the knowledge gap in semileptonic $B\rightarrow X_c\ell\nu$ decays

This paper summarizes the current status of exclusive semileptonic $B\rightarrow X_c\ell\nu$ branching fractions, identifies unmeasured components dominated by baryonic and $D_s$ final states, and proposes specific candidates and simplified models to close the gap with inclusive measurements.

Squeezed-state radiation in shockwave scattering: QCD-Gravity double copy

This paper demonstrates that multi-gluon and multi-graviton radiation in strong field shockwave scattering can be modeled as generalized Susskind-Glogower squeezed coherent states via the QCD-Gravity double copy, revealing that large squeezing parameters in nearly minimal uncertainty configurations could produce gravitational wave quantum noise exceeding the sensitivity of current and future detectors.

Solution of the boundary problem for the axial-vector field in the hard-wall AdS/QCD model

This paper presents a solution to the boundary problem for the axial-vector field in the hard-wall AdS/QCD model by deriving fundamental solutions to a homogeneous ordinary differential equation and employing an iterative method to establish sufficient conditions for the Fredholm solvability of the resulting integral equation.

Einstein-de Haas effect and induced rotation in QCD matter

This study reports the first identification of the Einstein-de Haas effect in QCD matter, demonstrating that magnetic-field-induced spin alignment alone can generate collective rotation comparable to fluid vorticity in heavy-ion collisions, thereby establishing hot QCD matter as a self-vortical magnetofluid.
