Weak coupling expansion of a chiral gauge theory on a lattice in the overlap formulation [PDF]
, 1997 Weak coupling expansion of a chiral gauge theory on a lattice is discussed in the overlap formulation. We analyze the fermion propagator and the fermion-fermion-gauge boson vertex in the one loop level.

Annalen der Physik, Volume 538, Issue 1, January 2026.The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Oblique corrections in general dark U(1) models
Journal of High Energy PhysicsWe investigate the impact of dark Abelian gauge bosons on the electroweak precision measurements at the one-loop level. The dark gauge boson couples to the standard model fermions generally via two kinds of mixing with the electroweak gauge bosons: the ...

Annalen der Physik, Volume 538, Issue 1, January 2026.Numerically exact quantum Monte Carlo calculations of bipolaron properties are used to estimate transition temperatures (T*) for Hubbard–Holstein models on face‐centre cubic (FCC) and body‐centre cubic lattices. Repulsion (U/W) can make bipolarons lighter and raise T*. Lattice properties leading to 1st order hopping means that T* is much higher for the

Classes of complete dark photon models constrained by Z-physics
Physics Letters BDark Matter models that employ a vector portal to a dark sector are usually treated as an effective theory that incorporates kinetic mixing of the photon with a new U(1) gauge boson, with the Z boson integrated out.

Disguising the Oblique Parameters
, 2006 We point out a set of operator identities that relate the operators corresponding to the oblique corrections to operators that modify fermion couplings to the gauge bosons as well as operators that modify triple gauge boson couplings. Such identities are

Advanced Physics Research, Volume 5, Issue 1, January 2026.In this work, we present the first in‐depth investigation of elasto‐mechanical, thermophysical, and optical properties of these compounds. In particular, we analyzed the directional dependence of the elastic properties, explored the optical response for different photon polarization directions, and examined potential industrial applications of these ...

Impact of the PDFs on the Z and W lineshapes at LHC
European Physical Journal C: Particles and Fields, 2020 The parton distribution functions (PDFs) of the proton play a role in determining the lineshape of Z and W bosons produced at the LHC. In particular, the mode of the gauge boson virtuality is shifted with respect to the pole due to the dependence of the ...
