Pentaquark Searches at CDF
نویسنده
چکیده
Experimental results of a search for the Ξ3/2(1860) cascade pentaquark state in data collected with the CDF 2 Detector in Run II at the Tevatron are presented. No evidence for these states in the neutral Ξπ and doubly charged Ξ−π− modes has been found. Preliminary upper limits on yields at 1862 MeV/c relative to the well established resonance Ξ(1530) are presented.

Pentaquark Searches at Cdf * Dmitry O. Litvintsev a (for Cdf Collaboration)
Searches for states, characterized by so-called exotic quantum numbers, i.e., quantum numbers that cannot be obtained from minimal (qq̄) or (qqq) configurations of standard mesons and baryons, have taken place since the introduction of QCD and quark model. Until recently, these searches yielded very little conclusive evidence for such states. During 2003, however, the situation has changed drama...
متن کاملThe X(3872) Meson and " Exotic " Spectroscopy at Cdf Ii —or Not?—
A spate of remarkable new hadrons reported in 2003 may lead to unequivocal proof of states beyond conventional qq̄ and qqq structure. Claimed baryonic states Θ, Φ, and Θc would consist of five quarks, and new D + sJ -states and/or X(3872) might contain four quarks. I review efforts to search for and study this “new” spectroscopy in p̄p-collisions with the CDF II detector. Pentaquark searches are ...

A review of the results in the inclusive and exclusive searches for pentaquark states obtained from the analysis of the data recorded at the BABAR experiment at the Stanford Linear Accelerator Center PEP-II B-Factory, is presented. Inclusive searches for the strange pentaquark states
متن کاملPentaquarks in high-energy colliding experiments: perspectives from HERA
Several issues related to pentaquark searches relevant for current and future high-energy colliding experiments are discussed. We make an attempt to explain why pentaquark candidates are not seen by some experiments, and what makes the HERA experiments so special in such searches.
متن کاملResults of the Searches for Narrow Baryonic States with Strangeness in Dis at Hera
Searches for narrow baryonic states in the K S p, Kp, Ξ π and Ξ̄ π decay channels are reported. The data were collected with the ZEUS detector at HERA using an integrated luminosity of 121 pb. The searches were performed in the central rapidity region of inclusive deep inelastic scattering at an ep centre-ofmass energy of 300–318 GeV for exchanged photon virtuality, Q, above 1 GeV. The results s...
