Book Description
This paper presents a direct measurement of the differential[ital B][sup+] and[ital B][sup 0] cross sections, [ital d[sigma]/dp[sub T]] in[ital p][ital[anti p]] collisions at[radical]s= 1.8 TeV using a sample of 74[ital pb][sup -1] accumulated by the Collider Detector at Fermilab (CDF). The cross sections are measured in the central pseudorapidity region[vert-bar][eta][vert-bar][lt] 1 for[ital p[sub T]]([ital B])[gt] 6.0 GeV/c by fully reconstructing the[ital B] meson decays[ital B][sup+][r-arrow][ital J/[psi]K[sup+]] and[ital B][sup 0][r-arrow][ital J/[psi]K[sup*0]](892), where[ital J/[psi]][r-arrow][mu][sup+][mu][sup -] and[ital K][sup*0][r-arrow][ital K][sup+][pi][sup -]. The prediction of next-to- leading order QCD is consistent with the shape of the differential cross section but is low by a factor of 2.1[+-]0.2[+-]0.3. The integrated[ital B] meson cross section for[ital p[sub T]]([ital B])[gt] 6.0 GeV/c is determined to be[sigma]([ital B][sup -]= 3. 54[+-]0.22[+-]0.53[mu][ital b].

Book Description
This paper presents the first measurement of the differential B[sup [+-]] and B[sup 0] cross-sections, d[sigma]/dp[sub [Tau]], in p[anti p] collisions at [radical]s = 1.8 TeV. The data sample used represents an integrated luminosity of 19.3 [+-] 0.8 pb[sup [minus]1] accumulated by the Collider Detector at Fermilab (CDF). The cross-sections are measured over the p[sub T] range 6--15 GeV/c in the central pseudorapidity region [vert-bar][eta][vert-bar]

Book Description
The authors present a new measurement of the inclusive and differential production cross sections of J/[psi] mesons and b-hadrons in proton-antiproton collisions at √s = 1960 GeV. The data correspond to an integrated luminosity of 39.7 pb−1 collected by the CDF Run II detector. They find the integrated cross section for inclusive J/[psi] production for all transverse momenta from 0 to 20 GeV/c in the rapidity range

Measurement of the Total and Differential Inclusive $\mathrm{B}^{+}$ Hadron Cross Sections in Pp Collisions at $\sqrt{s}

Category :
Languages : en
Pages :

Book Description
The total and differential cross sections for inclusive production of $\mathrm{B}^{+}$ hadrons are measured as a function of the $\mathrm{B}^{+}$ transverse momentum $p_{\mathrm{T}}^\mathrm{B}$ and rapidity $y^\mathrm{B}$ in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 49.4 pb$^{-1}$. The measurement uses the exclusive decay channel $\mathrm{B}^{+} \to \mathrm{J}/\psi \mathrm{K}^{+}$, with $\mathrm{J}/\psi$ mesons that decay to a pair of muons. The results show a reasonable agreement with theoretical calculations within the uncertainties.

Book Description
Here, we describe a measurement of the ratio of the cross sections times branching fractions of the Bc+ meson in the decay mode Bc+ → J/[psi][mu]+[nu] to the B+ meson in the decay mode B+ → J/[psi]K+ in proton-antiproton collisions at center-of-mass energy √s = 1.96 TeV. The measurement is based on the complete CDF Run II data set, which comes from an integrated luminosity of 8.7 fb-1. The ratio of the production cross sections times branching fractions for Bc+ and B+ mesons with momentum transverse to the beam greater than 6 GeV/c and rapidity magnitude smaller than 0.6 is 0.211 ± 0.012(stat)-0.020+0.021(syst). Using the known B+ → J/[psi]K+ branching fraction, the known B+ production cross section, and a selection of the predicted Bc+ → J/[psi][mu]+[nu] branching fractions, the range for the total Bc+ production cross section is estimated.
