Gauge boson production at the tevatron [PDF]
Nuclear Physics B - Proceedings Supplements, 2003 We present measurements on gauge boson production from data taken during 1994-1996 by the D0 and CDF detectors: the differential production cross section of the W boson as a function of the transverse momentum [1,2], the ratio of W and Z differential cross sections [3,4], direct photon cross-sections at {radical}s = 630 and 1800 GeV [5,6], and studies ...

Can two or more gauge bosons propagate in the light-front? [PDF]
arXiv, 2004 Gauge fields in the light-front are usually fixed via the nA=0 condition yielding the non-local singularities of the type (kn)^(-a)=0 and a=1,2,.. in the gauge boson propagator which must be addressed conveniently. In calculating this propagator for n noncovariant gauge bosons those non-local terms demand the use of a prescription to ensure causality ...

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 Quantum Technologies, EarlyView.This work proposes a photon subtraction scheme, termed ′photon culling′, that enables the selective extraction of a single photon based on its arrival time relative to other photons. This scheme enables the generation of multi‐photon Fock states with high fidelity and modal purity, demonstrating significant potential for quantum metrology applications ...

Gauge boson mass dependence and chiral anomalies in generalized massless Schwinger models
Journal of High Energy PhysicsI bosonize the position-space correlators of flavor-diagonal scalar fermion bilinears in arbitrary generalizations of the Schwinger model with n F massless fermions coupled to n A gauge bosons for n F ≥ n A .

Gauge Field Model With Massive Gauge Bosons [PDF]
arXiv, 1998 A gauge field model, which simultaneously has strict local gauge symmetry and massive gauge bosons, is discussed in this paper. The model has SU(N) gauge symmetry. In the limit $\alpha \longrightarrow 0$, the gauge field model discussed in this paper will return to Yang-Mills gauge field model. The important meaning of this model is that, without Higgs

Search for $HZZ'$ couplings at the LHC
, 2014 New physics models predict the possibility of extra neutral gauge bosons ($Z'$) associated with an extra $U(1)'$ gauge symmetry. We study the couplings of the Higgs boson to the $Z$ boson and $Z'$ boson predicted by the new physics models.

Synthesis, Structures, and Transport Properties of Quaternary Ba–Ag–Tr–As Materials (Tr = Ga, In)
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The synthesis, structures, and properties of two triel‐containing quaternary arsenides are investigated. The synthesis, structures, and properties of two quaternary barium–arsenide materials are presented. The first, Ba4Ag2.3In1.7As8, is a novel material with the monoclinic unit cell (P21/m space group).

Massive Abelian gauge bosons in front-form Hamiltonians [PDF]
, 2018 It is shown how gauge bosons can be supplied a mass term using the Higgs mechanism for the purpose of regulating Hamiltonians of Abelian gauge theories in the front form of quantum dynamics.

Journal of High Energy PhysicsThe described Dark Abelian Sector Model (DASM) extends the Standard Model (SM) by a “dark” sector containing a spontaneously broken U(1)d gauge group. Keeping this dark sector quite generic we only add one additional Higgs boson, one Dirac fermion, and ...
