Abstract

We present the first measurement of the ratio of branching fractions Β(Λ _b → Λ _c ⁺μ ^-¯ν _μ)/Β(Λ _b → Λ _c ⁺π ^-) based on 171.5 pb ^-1 of p¯p collisions at √s = 1.96 TeV taken with the CDF-II detector. In addition, we present measurements of Β(¯Β ⁰ → D* ⁺μ ^-¯ν _μ)/Β(¯Β ⁰ → D* ⁺π ^-) and Β(¯Β ⁰ → D ⁺μ ^-¯ν _μ/Β(¯Β ⁰ → D ⁺π ^-), which serve as control samples to understand the data and Monte Carlo used for the Λ _b analysis.

Measurement of the shape of the $Λ_{b}^{0} \to Λ_{c}^{+} μ^{-} {\bar{ν}}_{μ}$ differential decay rate

Journal Article Aaij, R. ; Adeva, B. ; Adinolfi, M. ; ... - Physical Review D

A measurement of the shape of the differential decay rate and the associated Isgur-Wise function for the decay Λ ⁰ _b→Λ ⁺ _cμ ^–¯νμ is reported, using data corresponding to 3 fb ^–1 collected with the LHCb detector in proton-proton collisions. The Λ ⁺ _cμ ^–¯ν _μ(+anything) final states are reconstructed through the detection of a muon and a Λ ⁺ _c baryon decaying into pK ^–π ⁺, and the decays Λ ⁰ _b→Λ ⁺ _cπ ⁺π ^–μ ^–¯ν _μ are used to determine contributions from Λ ⁰ _b→Λ* _c ⁺μ ^–¯νμ decays.

Measurement of the Ratio of the $B^{0} \to D^{* -} τ^{+} ν_{τ}$ and $B^{0} \to D^{* -} μ^{+} ν_{μ}$ Branching Fractions Using Three-Prong $τ$ -Lepton Decays

Journal Article Aaij, R. ; Adeva, B. ; Adinolfi, M. ; ... - Physical Review Letters

The ratio of branching fractions R( D* ^–) ≡ B( B ⁰ → D* ^–τ ⁺ν _τ)/B( B ⁰ → D* ^–μ ⁺ν _μ) is measured using a data sample of proton-proton collisions collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb ^–1. For the first time, R( D* ^–) is determined using the τ-lepton decays with three charged pions in the final state. The B ⁰ → D* ^–τ ⁺ν _τ yield is normalized to that of the B ⁰ → D* ^–π ⁺π ^–π ⁺ mode,more »« less

Measurement of the Λ ⁰ _b lifetime in Λ ⁰ _b → Λ ⁺ _cπ ^- decays at the Collider Detector at Fermilab

Thesis/Dissertation Mumford, Jonathan Reid

The lifetime of the Λ ⁰ _b baryon (consisting of u, d and b quarks) is the theoretically most interesting of all b-hadron lifetimes. The lifetime of Λ ⁰ _b probes our understanding of how baryons with one heavy quark are put together and how they decay. Experimentally however, measurements of the Λ ⁰ _b lifetime have either lacked precision or have been inconsistent with one another. This thesis describes the measurement of Λ ⁰ _b lifetime in proton-antiproton collisions with center of mass energy of 1.96 TeV at Fermilab's Tevatron collider.

Measurement of the absolute branching fraction for $Λ_{c}^{+} \to Λ μ^{+} ν_{μ}$

Journal Article Ablikim, M. ; Achasov, M. N. ; Ahmed, S. ; ... - Physics Letters B

Here, we report the first measurement of the absolute branching fraction for Λ _c ⁺ → Λμ ⁺ν _μ. This measurement is based on a sample of e ⁺e ^– annihilation data produced at a center-of-mass energy √s = 4.6 GeV, collected with the BESIII detector at the BEPCII storage rings. The sample corresponds to an integrated luminosity of 567 pb ^–1. The branching fraction is determined to be B(Λ _c ⁺ → Λμ ⁺ν _μ) = (3.49 ± 0.46(stat) ± 0.27(syst))%. In addition, we calculate the ratio B(Λ _c ⁺ → Λμ ⁺νμ)/B(Λ _c ⁺ → Λe ⁺ν _e)more »« less
