NA61.

                 One of physics goals of the NA61/SHINE experiment is a measurement of hadron production cross sections from proton-Carbon interactions at 31GeV/c for the T2K experiment at J-PARC. A precise knowledge of differential cross sections for pion and kaon production is of importance for improving the accuracy of neutrino flux simulations. The NA61 detector has a large angular acceptance, full coverage of the T2K phase space region, and good particle identification.

 

The physics program of the NA61/SHINE (SHINE = SPS Heavy Ion and Neutrino Experiment) experiment at CERN consists of three subjects: ([1],[2])

1. Measurements of hadron production in hadron-nucleus interactions needed for neutrino (T2K) and cosmic-ray (Pierre Auger and KASCADE) experiments,

2. Measurements of hadron production in proton-proton and proton-nucleus interactions as reference data for nucleus-nucleus reactions,

3. Measurements of energy dependence of hadron production properties in proton-proton, proton-nucleus, and nucleus-nucleus interactions with the aim to identify the properties of the onset of deconfinement and find evidence for the critical point of strongly interacting matter.

 

The NA61/SHINE detector is an upgrade of the NA49 experimental setup at CERN [3]. The upgrade mainly concerns the installation of the Forward TOF, a new Time Projection Chamber Read-Out, and a new Data Acquisition System. The Old Zero Degree Calorimeter (ZDC) will be substituted by the Projectile Spectator Detector (PSD). The layout of the NA61/Shine setup and main upgrades are shown in Figure 1.

 

 

New experimental information on hadron production in p+C interactions in the region of several tens of GeV is necessary for neutrino beam and cosmic ray event simulations. Even the information on mean multiplicities of the most abundant hadrons is still lacking. It is the region in which the interpolations performed using low energy and high energy models do not agree.

 

H− methode is based on the theoretical and experimental premise that the produced negative hadrons at incident energy consists mainly of negative pions with a few percent admixture of negative kaons, electrons from Dalitz decays of neutral mesons, and a negligible fraction of antiprotons. A Monte Carlo VENUS [1] model was used to obtain information on geometric acceptance and reconstruction efficiency, measurement smearing, decays, and non-pion admixture.

 

As a result of h− analysis corrected two dimensional momentum versus emission angle spectrum (Figure 2) and dn/dp distributions in polar angle slices were obtained for negatively charged pions produced from proton interactions.

 

As an example distributions of dn/dp in two selected angular intervals obtained using two different methods (h– method and dE/dx+TOF method)  are shown in Figure 3.
