Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.
At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.
Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.
This paper investigates the LHC phenomenology of a two-vector dark sector model, demonstrating that a binned analysis of the signature significantly improves sensitivity to parameter space regions consistent with the observed dark matter relic abundance compared to inclusive missing-transverse-momentum searches.
This paper presents a path-integral computation demonstrating that excitations of a massive worldsheet axion in QCD strings significantly alter the string breaking rate via a Schwinger-like mechanism by inducing a varying effective tension that can exponentially enhance or suppress quark-antiquark pair nucleation, offering crucial corrections for hadronisation models at colliders.
This paper investigates quantum anomalies of 1-form symmetries by computing the oriented and spin bordism groups of up to degree 8, thereby identifying new mixed perturbative and discrete anomalies in 5- and 7-dimensional theories and providing their physical interpretations through invertible phases and bordism invariants.
This paper extends the stochastic inflation paradigm to a wide class of fully nonlinear scalar-tensor theories by applying a gauge-agnostic coarse-graining procedure to the effective field theory of dark energy, thereby deriving consistent stochastic equations of motion for models such as Gauss-Bonnet, Horndeski, and multifield inflation within full General Relativity.
This paper argues that assuming a "discrete" vacuum geometry in the Minkowskian Higgs model justifies Dirac fundamental quantization by introducing thread-like topological defects that generate collective solid rotations, leading to a first-order phase transition characterized by the coexistence of rotational and superfluid thermodynamic phases within BPS monopole vacua.
This paper demonstrates that the functional renormalization group can accurately compute the universal probability distribution functions and large deviation rate functions of the order parameter for the three-dimensional Ising model at criticality, showing excellent agreement with numerical simulations.
This paper investigates the behavior of generalized Lemaitre time for rotating and charged black holes, establishing a relationship between its finiteness, the forward-in-time condition, and kinematic censorship to provide a new explanation for why particle collisions inside the horizon cannot yield infinite center-of-mass energy.
This paper investigates primordial black hole formation in quadratic gravity by combining a first-order perturbative analysis around General Relativity with a non-perturbative Einstein-frame numerical study of the scalaron field to determine the critical overdensity threshold for collapse.
This paper employs the S-matrix framework to derive formulas for entanglement entropy in high-energy elastic and inelastic two-particle scatterings, demonstrating through neutron-proton data that inelastic processes generate greater overall entanglement than elastic ones.
This paper proposes a method to realize quintom dark energy, favored by recent DESI DR2 observations, by coupling dark energy to the Nieh-Yan density within teleparallel gravity, thereby eliminating perturbative instabilities associated with the crossing and predicting parity violation in gravitational waves.
