Article: Search for exotic baryons with hidden strangeness in proton diffractive production at the energy of 70 GeV
[show abstract] [hide abstract]
ABSTRACT: The first preliminary results from the upgraded SPHINX spectrometer, working in the proton beam with the energy of 70 GeV of the IHEP accelerator, are presented. The data for the reaction p + N ⊒ [Σ0 K +] + N based on new statistics are in good agreement with our previous data and strongly support the existence of the X (2000) state (with an increase in statistics for this state by a factor of ∼5). We also observed radiative decay of Λ(1520) → Λγ. The significant increase in statistics for many diffractive-production reactions will allow us to study them in great detail.Physics of Atomic Nuclei 04/2012; 65(11):2070-2076. · 0.57 Impact Factor -
Article: Study of the K− → e−νπ0 decay
[show abstract] [hide abstract]
ABSTRACT: The decay K − → e − νπ 0 has been studied using in-flight decays detected with the ISTRA+ setup working at the 25-GeV negative secondary beam of the U-70 PS. About 130K events were used for the analysis. The λ + parameter of the vector form factor has been measured: λ +=0.0293±0.0015(stat.)±0.002(syst.). The limits on the possible tensor and scalar couplings have been derived: f T/f +(0)=−0.045±0.060(stat.) and f S/f +(0)=−0.019 −0.016 +0.025 (stat.).Physics of Atomic Nuclei 10/2002; 65(11):2064-2069. · 0.57 Impact Factor
