The Weak Charge of the Proton and New Physics [PDF]

, 2003
We address the physics implications of a precision determination of the weak charge of the proton, QWP, from a parity violating elastic electron proton scattering experiment to be performed at the Jefferson Laboratory.

Operator analysis for precision electroweak physics

Physics Letters B, 1991
The impact of new physics associated with the Higgs sector on precision electroweak physics is examined. We assume that at low energies the degrees of freedom are those of the standard model with minimal particle content (i.e., three generations of quarks and leptons and one Higgs doublet), and that the new physics is very weakly coupled to the quarks ...

Electron and photon structure functions at two loops

Journal of High Energy Physics
We present a fully analytic computation of the complete electron and photon structure functions, or QED lepton parton distribution functions (PDFs) up to two-loop order.

Unification of Conformal and Fuzzy Gravities With Internal Interactions Resulting in SO(10) and a Possible Probe Through Stochastic Gravitational Wave Background

Fortschritte der Physik, Volume 73, Issue 9-10, October 2025.
Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

Unveiling atomic electron motion effects in e + e − high energy collisions at NA64

Journal of High Energy Physics
Atomic electron motion is responsible for well-studied effects observed in low-energy (MeV-scale) processes. Recently, interest in this phenomenon has also emerged within the high-energy physics community, due to its potential to increase significantly ...

The Gauge-Higgs legacy of the LHC run II

SciPost Physics, 2019
We present a global analysis of the Higgs and electroweak sector based on LHC Run II and electroweak precision observables. We show which measurements provide the leading constraints on Higgs-related operators, and how the achieved LHC precision makes

Effective field theory of precision electroweak physics at one loop

Physics Letters B, 2013
The one loop effects of two dimension-six operators on gauge boson self energies are computed within an effective field theory framework. These self energies are translated into effects on precision electroweak observables, and bounds are obtained on the operator coefficients.

Electroweak Physics, Experimental Aspects

, 1999
Collider measurements on electroweak physics are summarised. Although the precision on some observables is very high, no deviation from the Standard Model of electroweak interactions is observed.

Holomorphic field theories and higher algebra

Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Entanglement and Bell nonlocality in τ + τ − at the BEPC

Journal of High Energy Physics
Quantum entanglement and Bell nonlocality are two phenomena that occur only in quantum systems. In both cases, these are correlations between two subsystems that are classically absent.
