Correlations between pions from different W’s in e+e- +W+W- events are studied using data collected by the DELPHI detector at LEP running at a centre-of-mass energy of 172 GeV in 1996. At the present level of statistics, no enhancement of the correlation function above that expected from a pair of uncorrelated W’s is observed at small values of the four-momentum difference of the pions.

Abstract
Correlations between pions from different W’s in e+e- +W+W- events are studied using data collected by the DELPHI detector at LEP running at a centre-of-mass energy of 172 GeV in 1996. At the present level of statistics, no enhancement of the correlation function above that expected from a pair of uncorrelated W’s is observed at small values of the four-momentum difference of the pions.File in questo prodotto:
