Performance of a magnetized total absorption calorimeter between 15 GeV and 140 GeV

Study of Hadronic and Electromagnetic Shower Development between 10 and 140 Gev by an Iron - Scintillator Calorimeter

Results are presented on the analysis of CDHS test beam data using an iron-scintillator calorimeter exposed to electrons and pions in the energy range 10 to 140 GeV. Shower development is studied in order to extract information on calorimetric response to electrons and pions, longitudinal and transverse shower profiles, shower containment and correlations, muon punch through and the effect on e...

PEP-N: A 0.8 GeV × 3.1 GeV Collider at SLAC

The PEP-N project is a proposed new e+e− collider at SLAC to operate in the center of mass energy range of 1.0 GeV to 3.1 GeV. PEP-N consists of a new Very Low Energy electron Ring VLER (< 800 MeV) to collide with the PEP-II e+ Low Energy Ring LER (3.1 GeV) parasitically to PEP-II operation for BaBar. Since the e+ ring has a fixed energy, the very low energy ring needs an energy range of 100 Me...

Cosmic Rays I . The cosmic ray spectrum between 10 4 GeV and 3 10 9 GeV

Based on a conjecture about the diffusion tensor of relativistic particles perpendicular to the magnetic field at a shock, and considering particle drifts, I develop a theory to account for the Cosmic Ray spectrum between 10 GeV and 3 10 GeV. The essential assumption is that the free mean path perpendicular to the magnetic field is independent of energy and has the scale of the thickness of the...

MPI - PhE / 2000 - 10 May 15 , 2000 α S Evolution from 35 GeV to 202 GeV and Flavour Independence

= 200 Gev

We present the results on the mid-rapidity φ meson production in the K + K − decay channel in Au + Au collisions at √ s N N = 200 GeV measured by the PHENIX experiment at RHIC. The spectral shape of the φ resonance, studied at different collision centralities, is consistent with the particle data book. The transverse mass spectra are measured in four centrality bins. The inverse slopes (T), yie...
