Measurement of the differential branching fraction of the decay Λ0b→Λμ+μ− [PDF]

open access: yes, 2013
The differential branching fraction of the decay Λ0b→Λμ+μ− is measured as a function of the square of the dimuon invariant mass, q2. A yield of 78 ± 12 Λ0b →Λμ+μ− decays is observed using data, corresponding to an integrated luminosity of 1.0 fb−1 ...

Observation of and evidence for decays

open access: yesNew Journal of Physics, 2014
Measurements of the branching fractions of $B_{s}^{0}\to {{K}^{*\pm }}{{K}^{\mp }}$ and $B_{s}^{0}\to {{K}^{*\pm }}{{\pi }^{\mp }}$ decays are performed using a data sample corresponding to $1.0\ {\rm f}{{{\rm b}}^{-1}}$ of proton-proton collision data ...

Search for a standard model-like Higgs boson in the μ+μ− and e+e− decay channels at the LHC

open access: yesPhysics Letters B, 2015
A search is presented for a standard model-like Higgs boson decaying to the μ+μ− or e+e− final states based on proton–proton collisions recorded by the CMS experiment at the CERN LHC. The data correspond to integrated luminosities of 5.0 fb−1 at a centre-

Angular analysis of the decay B0→K⁎0μ+μ− from pp collisions at s=8 TeV

open access: yesPhysics Letters B, 2016
The angular distributions and the differential branching fraction of the decay B0→K⁎(892)0μ+μ− are studied using data corresponding to an integrated luminosity of 20.5 fb−1 collected with the CMS detector at the LHC in pp collisions at s=8 TeV. From 1430

First Observation of the Rare Decay Mode K-long -> e+ e-

open access: yes, 1998
In an experiment designed to search for and study very rare two-body decay modes of the K-long, we have observed four examples of the decay K-long -> e+ e-, where the expected background is 0.17+-0.10 events.

Decomposition of Supercritical Linear-Fractional Branching Processes

open access: yesApplied Mathematics, 2013
It is well known that a supercritical single-type Bienyam -Galton-Watson process can be viewed as a decomposable branching process formed by two subtypes of particles: those having infinite line of descent and those who have finite number of descendants.

Measurement of the Bs0→μ+μ− decay properties and search for the B0 → μ+μ− decay in proton-proton collisions at s=13TeV

open access: yesPhysics Letters B, 2023
Measurements are presented of the Bs0→μ+μ− branching fraction and effective lifetime, as well as results of a search for the B0→μ+μ− decay in proton-proton collisions at s=13TeV at the LHC. The analysis is based on data collected with the CMS detector in

Measurement of Inclusive Radiative B-meson Decays with a Photon Energy Threshold of 1.7 GeV

open access: yes, 2009
Using 605/fb of data collected at the Upsilon(4S) resonance we present a measurement of the inclusive radiative B-meson decay channel, B to X_s gamma. For the lower photon energy thresholds of 1.7, 1.8, 1.9 and 2.0GeV, as defined in the rest frame of the

Study of charmonium production in b -hadron decays and first evidence for the decay Bs0 [PDF]

open access: yes, 2017
Using decays to φ-meson pairs, the inclusive production of charmonium states in b-hadron decays is studied with pp collision data corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb experiment at centre-of-mass energies of 7 and ...
