Charm hadroproduction results from Selex The SELEX Collaboration
نویسندگان
چکیده
The SELEX experiment (E781) is 3-stage magnetic spectrometer for a high statistics study of hadroproduction of charm baryons out to large xF using 650 Gev Σ , π and p beams. The main features of the spectrometer are: a high precision silicon vertex system, powerful particle identification provided by TRD and RICH, forward Λs decay spectrometer and 3-stage lead glass photon detector. An experiment overview and spectrometer features are shown. Reconstructed charm states and results on Λc, D + particles and antiparticles produced by Σ, π and p beams at xF > 0.3 and asymmetry for Λc are presented.

In parallel to charm hadroproduction the experiment Selex (E781) at Fermilab is pursuing a rich hyperon physics program. Selex employs a 600 GeV/c beam consisting of 50 % Σ− and π− each. The three-stage magnetic spectrometer covering 0.1 ≤ xF ≤ 1.0 features a high-precision silicon vertex system, broad-coverage particle identification using TRD and RICH, and a three-stage lead glass photon calo...
متن کاملΛ + c − Λ − c production asymmetries in two component models
Experiments on charm hadroproduction have shown a substantial difference in the production of charm and anticharm hadrons. In this work we study Λ+ c and Λ c inclusive production in p−N interactions in the framework of two component models. We show that the recombination two component model gives a qualitatively and quantitatively good description of Λ c production while the intrinsic charm mod...
متن کاملHadronic Production of the Doubly Charmed Baryon Ξcc with Intrinsic Charm
We study effects of the intrinsic charm on the hadronic production of Ξcc at SELEX, Tevatron and LHC. By taking the intrinsic charm into account, the cross-section of the production at SELEX is changed significantly. In contrast, at LHC and Tevatron the change is small because the gluon-gluon fusion becomes dominant. The measured cross-section at SELEX is much larger than the prediction based o...
متن کاملCharm Production and Cross Sections for D Mesons
New high statistics, high resolution fixed target experiments producing 10 10 fully reconstructed charm particles are allowing a detailed study of the charm sector. Recent results on charm quark production from Fermilab fixed target experiments E-791, SELEX and FOCUS are presented. INTRODUCTION This review contains recent results from three Fermilab fixed target experiments dedicated to study c...
متن کاملMeasurement of the Σ− Charge Radius at Selex
The charge radii of Σ and π have been determined by direct elastic scattering on shell electrons. The measurement was performed in the framework of the Selex (E781) charm hadroproduction experiment at Fermilab which employs a 600 GeV/c high-intensity Σ/π beam and a three-stage magnetic spectrometer covering 0.1 ≤ xF ≤ 1.0. Scattering angles and momenta of both hadron and electron were measured ...
