Hollowness in $pp$ Scattering

COULOMB INTERFERENCE IN HIGH-ENERGY pp AND ¯pp SCATTERING.

Auditory detection of hollowness.

The airborne sounds produced by freely vibrating hollow and solid bars were synthesized according to the equations of bar motion from theoretical acoustics, and were presented to listeners over headphones. In a two-interval, forced-choice task, listeners were asked to distinguish between the hollow and solid bar sounds as bar length was varied at random from one presentation to the next. All ot...

A Multiparton Model for pp / pp Inelastic Scattering

We have applied a geometrical approach to study pp / pp inelastic scattering over the range of center mass energies from 44.5 to 900 GeV. The multiplicity distributions are described by multiple parton-parton collisions without free parameters. The output seems to be consistent with data and the results are discussed. Exploring the possible connection between impact parameter representation of ...

Hollowness perception with noise-reduction hearing aids.

The efficacy of "noise-reduction" hearing aids in reducing the hollowness perception of one's own voice during vocalization was examined. Binaural Siemens 283 ASP hearing aids were worn by 2 groups of listeners, one with primarily high-frequency loss (Group A) and one with loss in both high- and low-frequencies (Group B). Electroacoustic parameters on the hearing aids were adjusted initially fo...

Multiple photon effects in pp scattering at SSC energies ∗

The Monte Carlo program SSCYFS2 is used in conjunction with available parton distribution functions to calculate the effects of multiple photon radiation on pp scattering at SSC energies. Effects relevant to precision SSC physics such as Higgs discovery and exploration are illustrated. Supported in part by the Texas National Research Laboratory Commission for the Superconducting Super Collider ...
