Measurement of K^0_e3 form factors
NA48 collaboration
The semileptonic decay of the neutral K meson, KL -> pi e nu (Ke3), was used to study the strangeness-changing weak interaction of hadrons. A sample of 5.6 million reconstructed ev…
Measurement of the branching ratio of the decay KL -> pi e nu and extraction of the CKM parameter |Vus|
NA48 collaboration
We present a new measurement of the branching ratio R of the decay KL -> pi e nu (Ke3), relative to all charged KL decays with two tracks, based on data taken with the NA48 detecto…
System Size and Centrality Dependence of the Balance Function in A + A Collisions at s(NN)^(1/2) = 17.2 GeV
NA49 Collaboration
Electric charge correlations were studied for p+p, C+C, Si+Si and centrality selected Pb+Pb collisions at GeV with the NA49 large acceptance detector at the…
Multiplicity fluctuations in nuclear collisions at 158 A GeV
M Rybczynski
System size dependence of multiplicity fluctuations of charged particles produced in nuclear collisions at 158 A GeV was studied in the NA49 CERN experiment. Results indicate a non…
Omega and Antiomega production in central Pb+Pb collisions at 40 and 158 AGeV
The NA49 collaboration, C. Alt
Results are presented on Omega production in central Pb+Pb collisions at 40 and 158 AGeV beam energy. Given are transverse-mass spectra, rapidity distributions, and total yields fo…
Event-by-Event Fluctuations of Particle Ratios in Central Pb+Pb Collisions at 20 to 158 AGeV
Christof Roland
In the vicinity of the QCD phase transition, critical fluctuations have been predicted to lead to non-statistical fluctuations of particle ratios, depending on the nature of the ph…
Rapidity and transverse momentum dependence of pion-pion Bose-Einstein correlations measured at 20, 30, 40, 80, and 158 AGeV beam energy
Stefan Kniege
Preliminary results on pion-pion Bose-Einstein correlations in central Pb+Pb collisions measured by the NA49 experiment are presented. Rapidity as well as transverse momentum depen…
