The precise statement of the equivalence theorem, between the longitudinally polarized states of a massive gauge boson and the corresponding goldstone mode, is discussed when the amplitude in question depends on masses of other particles (e.g., the Higgs boson) in the theory.

Measurement of the W boson helicity in t ¯ t decays

The recent discovery of a Higgs boson at the LHC is a milestone in the quest to understand electroweak symmetry breaking. It is an important particle because it is responsible for the Higgs mechanism by which all particles acquire mass. The existence of a particle with zero spin suggests the need for new physics beyond the standard model. Z  bosons are known to naturally exist in well-motivate...

We present a search for the standard model Higgs boson produced in association with a Z boson in data collected with the CDF II detector at the Tevatron, corresponding to an integrated luminosity of 9.45  fb(-1). In events consistent with the decay of the Higgs boson to a bottom-quark pair and the Z boson to electron or muon pairs, we set 95% credibility level upper limits on the ZH production ...

Methods for measuring the W -boson properties at hadron colliders are discussed. It is demonstrated that the ratio between the W and Z-boson observables can be reliably calculated using perturbative QCD, even when the individual W and Z-boson observables are not. Hence, by using a measured Zboson observable and the perturbative calculation of the ratio of the W over Z-boson observable, we can a...

The top quark, the W-boson and the Higg boson form an interesting triptych of elementary particles. In the Standard Model knowing the mass of two of these particles, usually the top quark and W-boson, we can predict the mass of the third, the Higgs boson. Therefore in this proceedings I will primarily cover the following topics, top quark physics, W-boson mass and the light Higgs boson at the p...

Working with ytterbium ~Yb!, we demonstrate dual-isotope magneto-optic traps of extreme experimental simplicity yet containing either fermion-boson or boson-boson isotope pairs. Pairs studied include Yb1Yb ~a fermion-boson mixture! and Yb1Yb and Yb1Yb ~boson-boson mixtures!. Trapping is performed using the Yb (6s)S0-(6s6p) P1 transition, an uncooled thermal source, and bichromatic trapping beam...

Large Hadron Collider (LHC) experiments this year have shown the existence of a new boson that resembles the Higgs boson. Although it is known that this particle has couplings to other particles that increase with their masses, the spin of the newly discovered boson is undetermined as of yet. The Higgs boson has been predicted to be a spin 0 particle. The LHC boson is not a spin 1 particle, sug...
