Recent Results of Na48 on Neutral Kaon Rare Decays
نویسنده
چکیده
A primary proton beam from the CERN Super Proton Synchrotron is driven to a beryllium target (KL target). After a sweeping magnet and some collimators, a neutral beam is formed. The last collimator exit is located 126 m downstream of the target (see Fig. 1). The primary protons not interacting in the KL target are deflected by a bent crystal, forming a secondary proton beam that is transported to a second target (KS target, identical to the first one). After 6 m of sweeping and collimation, a second neutral beam, quasi-parallel to the first one, is sent to the decay region.

متن کاملNew Results in Kaon Physics from Na48 and Ktev
In the recent year many new results from kaon decays have been reported from both the NA48 experiment at CERN and the KTeV experiment at Fermilab. Both experiments have new and improved measurements of the parameter Re( ′/ ) of direct CP violation in the neutral kaon system. Also several new results on rare and very rare KL decays were reported. In addition, the NA48 collaboration has performed...
متن کاملResults on charged kaon and hyperon decays from NA 48
Recent results from the NA48/1 and NA48/2 experiments at the CERN SPS are presented. NA48/2 carried out data taking in 2003 and 2004 collecting charged kaon decays: branching ratios and form factors have been measured for the rare K→πee, K→πγγ and K→πeeγ decays. The NA48/1 experiment has taken data in 2002 using only the KS beam at an increased intensity measuring neutral hyperon radiative deca...
متن کاملNew Results from Na48 Experiment on Neutral Kaon Rare Decays
The NA48 experiment at CERN SPS, described in detail elsewhere, has been designed to measure the direct CP violation parameter R(ǫ/ǫ) in twopion decays of neutral kaons. However, the quality of its simultaneous KL and KS beams , high resolution detectors, fast trigger and performing data acquisition system allow to investigate at the same time rare decays of neutral kaons and neutral hyperons. ...
متن کاملResults from the NA48 experiment on rare neutral kaon decays
New and recent measurements of the branching ratios of rare decays of neutral KS and KL mesons are presented. The results have been extracted from data collected during the NA48 ′/ runs as well as in a special high intensity KS and hyperon run. In particular the presentation focuses on the decay of KL → πγγ, KS → π0e+e− and KS → γγ. The prospects of future programs aiming to study direct CP vio...
