Inclusive J / ψ and ψ ( 2 S ) Production from B Decay in pp̄ Collisions
Using information on B-meson fragmentation functions from CERN LEP 1 and adopting the nonrelativistic QCD factorization formalism proposed by Bodwin, Braaten, and Lepage, we predict the transverse-momentum distribution of J/ψ mesons originating from the inclusive decays of b hadrons produced in pp̄ collisions at the Fermilab Tevatron. We determine the relevant colour-octet charmonium matrix elem...

متن کاملInclusive B-decay Spectra and Ir Renormalons
B-decay physics is gradually turning into a field of precision phenomenology. Inclusive decay measurements provide some of the most robust tests of the standard model. Classical examples are the rate of B̄ −→ Xsγ decays [1] and constraints on the unitarity triangle through the measurement of Vub from charmless semileptonic decays [2]. The advantage of inclusive measurements over exclusive ones i...
متن کاملInclusive Search for Squarks and Gluinos Production and Search for Sbottom from Gluino Decay at CDF
Supersymmetry (SUSY) [1] is regarded as one of the most promising fundamental theories to describe physics at arbitrary high energy beyond the Standard Model. In mSUGRA [2] symmetry breaking is achieved via gravitational interactions and the vast SUSY parameter space is reduced to only five parameters: the common trilinear coupling at the GUT scale A0; the sign of the Higgsino mixing parameter ...
