“…Likewise, additional terms which are proportional to m l appear in M þÀ , M Àþ , and M 00 . In particular, the neutrino exchange diagram produces an extra term which grows proportional to E [5] in the high energy limit. This term is canceled by the Higgs exchange diagram.…”

We consider the prospects for detecting effects due to the Higgs exchange diagram in high energy µ + µ − , e + e − , and τ + τ − collisions producing a pair of W bosons. The processes l + l − → W + W − (with l = µ, e, τ ) are analyzed, analytically and via numerical simulations, to determine the center of mass energy, √ s H , where the effects from Higgs exchange become relevant. The scaling of √ s H with the mass of the incoming leptons is also studied. Special consideration is given to the W + W − → l ± ν l jj final state after experimental acceptance cuts are imposed. Angular cuts are shown to be able to significantly lower √ s H .

“…In 1974, Joglekar [5] showed that S-matrix unitarity forces the couplings of the electroweak gauge bosons and the Higgs boson to take the form of SM couplings at asymptotically high energies. This implies that, for nonzero lepton masses, Higgs boson exchange has to contribute to the process l þ l À !…”

“…This fact holds for all three ǫ i and in all amplitudes. If all external particles are in the longitudinal polarization state, there is for many amplitudes a cancellation in this sum of one power of s in the standard term (see [4]). Simultaneously there is a cancellation of one power of s in the ǫ W Φ -and the ǫ W -terms, which demonstrates the special form of L W Φ and L W as far as vector-boson self-couplings are concerned.…”

The high-energy behavior of vector-boson scattering amplitudes is examined within an effective theory for non-standard self-interactions of electroweak vector-bosons. Irrespectively of whether this theory is brought into a gauge invariant form by including non-standard interactions of a Higgs particle I find that terms that grow particularly strongly with increasing scattering energy are absent. Different theories are compared concerning their high-energy behavior and the appearance of divergences at the oneloop level.

“…Hawkins" states that peripheral vasoconstriction in response to noise supports the findings that endolymphatic oxygen tension is reduced during and after noise exposure, thus augmenting the fact of temporary threshold shift, whereas Joglekar et al 13 found that the inhalation of oxygen during noise exposure results in the reduction of temporary threshold shift and also speeds recovery.…”

Previous research found a relationship between stressprone personality (pattern A) and noise-induced vasoconstriction in normal-hearing adult subjects. The present research sought evidence for a possible relationship between susceptibility to high-frequency noise-induced permanent threshold shift (NIPTS) found among industrial workers and the vasoconstrictive behavior of the same workers when they were exposed to high-intensity noise. It was hypothesized that pattern A workers would show more vasoconstriction in the presence of high-intensity noise, and hence more susceptibility to NIPTS, than pattern B (non-stress-prone) workers. The 35 male subjects tested were divided into two groups. Group I contained 16 subjects who showed significant vasoconstriction in noise; group I subjects were clearly pattern A types. Group II contained 19 subjects who did not show significant vasoconstriction in noise. Group II contained mostly pattern B but a few pattern A subjects. Unexpectedly, it was the group II subjects who showed the most susceptibility to NIPTS; the difference between the means of the two groups was statistically significant ( p 2 0.001). The explanation for this unexpected finding is obscure.
