TRANSVERSE ENERGY AND MULTIPLICITY DISTRIBUTIONS OF P-P AND A+A INTERACTIONS

Data from AGS-E802 have been presented at the recent HIPAGS workshop at BNL1, published in journals 2,3,4 and in conference proceedings (St. Malo 5, Moriond 6), to which the reader is referred. Two results are mentioned here. The Lead Glass distribution dE(T)0/d-eta from central O + Au collisions 5 can be compared to the spectrometer dn(pi-)/dy from central Si + Au collisions4. The agreement of the two distributions is excellent and confirms that the estimated 5,6 position and value of the maximum in the distribution eta(max, dE(T)/d-eta)max, and the width DELTA-eta-FW H M, from the PbGl data are reasonable, and that nothing exceptional is occurring outside of the PbGl acceptance. Additionally, these data, and previous measurements of pseudorapidity distributions of multiplicity and Transverse Energy at both the AGS and CERN are analyzed in an acceptance-independent and model-independent method, with the conclusion that simple considerations of nuclear geometry do not provide an explanation of the different square-root s N N dependences observed in O-16 + Au and p-p reactions.
