First results of spherical GEMs
Serge Duarte Pinto, Matteo Alfonsi, Ian Brock +7
We developed a method to make GEM foils with a spherical geometry. Tests of this procedure and with the resulting spherical GEMs are presented. Together with a spherical drift elec…
Spherical GEMs for parallax-free detectors
Serge Duarte Pinto, Matteo Alfonsi, Ian Brock +7
We developed a method to make GEM foils with a spherical geometry. Tests of this procedure and with the resulting spherical \textsc{gem}s are presented. Together with a spherical d…

Measurement of K^{0}_{\mu3} form factors
The NA48 Collaboration
This paper reports on a new high precision measurement of the form factors of the K_{L}\to π^{\pm} μ^{\mp} ν_μ decay. The data sample of about 2.3 events was recorde…
Measurement of the Ratio Gamma(KL -> pi+ pi-)/Gamma(KL -> pi e nu) and Extraction of the CP Violation Parameter |eta+-|
NA48 Collaboration
We present a measurement of the ratio of the decay rates Gamma(KL -> pi+ pi-)/Gamma(KL -> pi e nu), denoted as Gamma(K2pi)/Gamma(Ke3). The analysis is based on data taken during a…
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…
