This paper presents the first full-color, three-loop QCD helicity amplitudes for Higgs boson plus three-parton scattering in the heavy-top effective theory, revealing that sub-leading color contributions are numerically significant and providing compact analytic expressions essential for precision LHC phenomenology.
This paper presents a comprehensive analysis of theoretical and experimental constraints on the real singlet extension of the Standard Model, emphasizing its potential to ensure absolute vacuum stability and facilitate electroweak baryogenesis while outlining the prospects for future Higgs self-coupling measurements and direct scalar searches to further probe its parameter space.
Using the JEWEL event generator, this study proposes a strategy to mitigate selection bias in heavy-ion collisions by re-clustering small-radius jets into "trimmed" jets, demonstrating that while this approach recovers some medium-induced broadening signals, the full effect is best observed by analyzing the radial profiles of sub-leading subjets beyond their cone radii.
This paper demonstrates that time-averaged entangling power serves as an effective operator-level diagnostic for distinguishing between manifest symmetry and parameter-dependent hidden symmetries in the Quantum Rabi model family, revealing distinct spectral responses such as peaks at integer-bias points for the asymmetric model and dips for the Jaynes-Cummings limit.
This paper validates the composite worldline instanton approach for calculating the nonperturbative decay of charged particles in constant electric and magnetic fields by demonstrating its agreement with self-energy and wave function overlap methods, while also exploring its potential application to proton decay and the effects of final-state entanglement.
This paper proposes and evaluates three complementary methods—ADAF-like flares from scalar clump encounters with Kuiper Belt Objects, atomic clock searches for oscillating fundamental constants, and astrometric microlensing—to constrain the properties of scalar field dark matter, demonstrating that Gaia-like astrometry can already probe compact clumps at the percent level for masses above .
This paper investigates the potential of photon-induced two-photon production in ultraperipheral heavy-ion collisions and at the Electron-Ion Collider to detect the scalar molecular candidate by calculating dressed cross sections that reveal a characteristic near-threshold line-shape distortion rather than a simple narrow peak.
This paper proposes and validates a novel experimental geometry utilizing 90-degree scattering to enable direct, single-shot measurement of radiation reaction energy losses in high-intensity laser-electron collisions through simultaneous pre- and post-collision electron beam spectrum analysis.
This paper proposes using the three-dimensional correlation of galaxy polarization-rotation angles to measure the amplitude and spatial coherence scale of ultralight axion-like particles, offering a geometric late-time probe capable of detecting sub-degree correlated rotations and constraining axion mass and coupling parameters.
This paper proposes a modified CP-violating observable, , which isolates the real part of the interference term to circumvent numerical cancellations and eliminate smooth background contributions, thereby providing a robust theoretical framework validated via the decay in the PQCD approach for detecting localized CP violation at future colliders.
