Measurement of the rare decay pi0 -> e+ e-
E. Abouzaid
The branching ratio of the rare decay pi0 -> e+ e- has been measured precisely, using the complete data set from the KTeV E799-II experiment at Fermilab. We observe 794 candidate p…
Measurement of the Alpha Asymmetry Parameter for the Omega- to Lambda K- Decay
HyperCP Collaboration, Y. C. Chen, R. A. Burnstein +33
We have measured the alpha parameter of the Omega- to Lambda K- decay using data collected with the HyperCP spectrometer during the 1997 fixed-target run at Fermilab. Analyzing a s…
Measurements of the Branching Fractions and Decay Distributions for KL->πμνγand KL->πeνγ
T. Alexopoulos, T. Andre, M. Arenton +56
We present measurements of R_Kl3rad = Gamma(KL->π\ellνγ; Egcm > 10 MeV)/Gamma(KL->π\ellν), where ell = mu or e, and Egcm is the photon energy in the kaon rest frame. These measurem…
Measurements of Semileptonic KL Decay Form Factors
KTeV Collaboration, T. Alexopoulos
We present new measurements of KL semileptonic form factors using data collected in 1997 by the KTeV (E832) experiment at Fermilab. The measurements are based 1.9 million KL->pi e…
Measurements of KL Branching Fractions and the CP Violation Parameter |eta+-|
KTeV Collaboration, T. Alexopoulos
We present new measurements of the six largest branching fractions of the KL using data collected in 1997 by the KTeV experiment (E832) at Fermilab. The results are B(KL -> pi e nu…
Search for the Rare Decay KL --> pi0 ee
KTeV collaboration, A. Alavi-Harati
The KTeV/E799 experiment at Fermilab has searched for the rare kaon decay KL--> pi0ee. This mode is expected to have a significant CP violating component. The measurement of its br…
Measurements of the Decay KL->e+e-mu+mu-
The KTeV Collaboration
The KTeV experiment at Fermilab has isolated a total of 132 events from the rare decay KL->e+e-mu+mu-, with an estimated background of 0.8 events. The branching ratio of this mode…
Measurements of Direct CP Violation, CPT Symmetry, and Other Parameters in the Neutral Kaon System
KTeV Collaboration, A. Alavi-Harati
We present a series of measurements based on K -> pi+pi- and K -> pi0pi0 decays collected in 1996-1997 by the KTeV experiment (E832) at Fermilab. We compare these four K -> pipi de…
Hadroproduction of the Chi1 and Chi2 States of Charmonium in 800 GeV/c Proton-Silicon Interactions
E771 Collaboration
The cross sections for the hadroproduction of the Chi1 and Chi2 states of charmonium in proton-silicon collisions at sqrt{s}=38.8 GeV have been measured in Fermilab fixed target Ex…
Search for the Decay K_L -> pi^0 nu nubar using pi^0 -> e^+ e^- gamma
A. Alavi-Harati
We report on a search for the decay K_L -> pi^0 nu nubar, carried out as a part of E799-II, a rare K_L decay experiment at Fermilab. Within the Standard Model, the K_L -> pi^0 nu n…
Observation of Direct CP Violation in K_{S,L} to ππDecays
KTeV Collaboration
We have compared the decay rates of K_L and K_S to π^+ π^- and π^0 π^0 final states using a subset of the data from the KTeV experiment (E832) at Fermilab. We find that the direct-…
Search for the decay K_L-> pi^0 nu nubar
J. Adams
We report on a search for the rare decay K_L -> pi^0 nu nubar in the KTeV experiment at Fermilab. We searched for two-photon events whose kinematics were consistent with an isolate…
