Abstract |
We present a search for core-collapse supernovae in the Milky Way galaxy, using the MiniBooNE neutrino detector. No evidence is found for core-collapse supernovae occurring in our Galaxy in the period from December 14, 2004 to July 31, 2008, corresponding to 98% live time for collection. We set a limit on the core-collapse supernova rate out to a distance of 13.4 kpc to be less than 0.69 supernovae per year at 90% C. L. |

Abstract |
MiniBooNE reports the first absolute cross sections for neutral current single pi(0) production on CH2 induced by neutrino and antineutrino interactions measured from the largest sets of NC pi(0) events collected to date. The principal result consists of differential cross sections measured as functions of pi(0) momentum and pi(0) angle averaged over the neutrino flux at MiniBooNE. We find total cross sections of (4.76 +/- 0.05(stat) +/- 0.76(sys)) X 10(-40) cm(2)/nucleon at a mean energy of < E-v > = 808 MeV and (1.48 +/- 0.05(stat) +/- 0.23(sys)) X 10(-40) cm(2)/nucleon at a mean energy of < E-v > = 664 MeV for v(mu) and (v) over bar (mu) induced production, respectively. In addition, we have included measurements of the neutrino and antineutrino total cross sections for incoherent exclusive NC 1 pi(0) production corrected for the effects of final state interactions to compare to prior results. |

Abstract |
We present a measurement of the top-quark pair-production cross section in p (p) over bar collisions at root s = 1.96 TeV using a data sample corresponding to 1.7 fb(-1) of integrated luminosity collected with the Collider Detector at Fermilab. We reconstruct t (t) over bar events in the lepton + jets channel, consisting of e nu + jets and μnu + jets final states. The dominant background is the production of W bosons in association with multiple jets. To suppress this background, we identify electrons from the semileptonic decay of heavy-flavor jets ("soft electron tags''). From a sample of 2196 candidate events, we obtain 120 tagged events with a background expectation of 51 +/- 3 events, corresponding to a cross section of sigma(t (t) over bar) = 7.8 +/- 2.4(stat) +/- 1.6(syst) +/- 0.5(lumi) pb. We assume a top-quark mass of 175 GeV/c(2). This is the first measurement of the t (t) over bar cross section with soft electron tags in run II of the Tevatron. |

Abstract |
We report a search for single top quark production with the CDF II detector using 2: 1 fb(-1) of integrated luminosity of p (p) over bar collisions at root s = 1.96 TeV. The data selected consist of events characterized by large energy imbalance in the transverse plane and hadronic jets, and no identified electrons and muons, so the sample is enriched in W -> tau nu decays. In order to suppress backgrounds, additional kinematic and topological requirements are imposed through a neural network, and at least one of the jets must be identified as a b quark jet. We measure an excess of signal-like events in agreement with the standard model prediction, but inconsistent with a model without single top quark production by 2.1 standard deviations (sigma), with a median expected sensitivity of 1.4 sigma. Assuming a top quark mass of 175 GeV/c(2) and ascribing the excess to single top quark production, the cross section is measured to be 4.9(-2.2)(+2.5) (stat + syst) pb, consistent with measurements performed in independent data sets and with the standard model prediction. |

Abstract |
The cross section for photon production in association with at least one jet containing a b quark has been measured in proton antiproton collisions at root s = 1.96 TeV. The data sample used corresponds to an integrated luminosity of 340 pb(-1) collected with the CDF II detector. Both the differential cross section as a function of photon transverse energy E-T(gamma) and the total cross section are measured and compared to a next-to-leading order prediction for the process. |
