Download Study of Charged Particle Species Produced in Association with B0, B-, and Bs Mesons in Proton - Anti-proton Collisions at S**(1/2) Book in PDF, ePub and Kindle
The authors study the yields of charged kaons, charged pions, and protons produced in association with B mesons produced in proton-antiproton collisions at center of mass energy 1960 GeV using 355 pb{sup -1} of data collected with the CDF detector at the Fermilab Tevatron. This is the first reported measurements of these yields at a hadron collider. The B mesons are reconstructed using their semileptonic decays: B{sup 0} {yields} {ell}{sup +}D{sup -}X, D{sup -} {yields} K{sup +}{pi}{sup -}{pi}{sup -}; B{sup 0} {yields} {ell}{sup +}D*{sup -}X, D*{sup -} {yields} {pi}{sup -}{bar D}{sup 0}, {bar D}{sup 0} {yields} K{sup +}{pi}{sup -}; B{sup +} {yields} {ell}{sup +}{bar D}{sup 0}X, {bar D}{sup 0} {yields} K{sup +}{pi}{sup -}; B{sub s}{yields}{ell}{sup +}D{sub s}{sup -}X, D{sub s}{sup -} {yields} {pi}{sup -}{phi}, {phi} {yields} K{sup +}K{sup -}. The K, {pi}, and p are identified using the Time of Flight detector (TOF), the CDF spectrometer, and the specific ionization (dE/dx) measured in the central drift chamber (COT). The fraction of charged kaons produced in association with {bar B}{sub s}{sup 0} mesons is found to be larger than the fraction produced in association with the {bar B}{sup 0} and B{sup -} mesons, as expected from naive models of heavy quark hadronization to mesons. The particle species yields are found to be in qualitative agreement with simulation of B meson production in hadron collisions from the PYTHIA Monte Carlo, although the yield of kaons around {bar B}{sub s}{sup 0} mesons is found to be larger in the simulation when compared to the data. These studies are important for understanding methods of identifying the flavor of {bar B}{sub s}{sup 0} mesons in measurement of {bar B}{sub s}{sup 0} flavor oscillations and charge conjugation-parity (CP) violation in {bar B}{sub s}{sup 0} meson decays.

Download DEUTERON PRODUCTION IN PROTON-PROTON COLLISIONS FROM 1.5 TO 3 GEV. Book in PDF, ePub and Kindle
The differential cross section for deuteron production in proton-proton collisions was measured for incident proton kinetic energies of 1.55, 2.5, and 2.9 GeV. Measurements were made at laboratory angles of 5.9, 11.55, 15.72 degrees, and at the two higher energies, at 20 degrees relative to the beam direction for deuteron laboratory momenta in the range 1.0-2.4 GeV/c. The center of mass differential cross section distributions obtained at the three energies of this experiment showed a general similarity to one another. The total deuteron production cross section decreased monotonically with incident proton kinetic energy. The cross section for production of deuterons associated with two or more pions had a maximum near 2 GeV. A search for pion resonances of unit isotopic spin in the mass range 400-1000 MeV through reactions of the form p + p to d + positive-x yielded evidence for RHO meson production. The laboratory distributions in momentum and angle of deuterons produced in proton-proton collisions at 2.9 GeV were found to be much different from those arising from proton-beryllium and proton-platinum collisions at the same energy.
