Understanding B Meson Branching Fractions [PDF]

open access: yesAIP Conference Proceedings, 2002
This is a discussion of the main branching fractions of B Meson decays (b → cW−). What has been measured and what remains unmeasured is summarized, and a plan to measure charged track multiplicity accompanying the D(*) meson in B decay is presented.

Amplitude analysis and branching-fraction measurement of D s + $$ {\mathrm{D}}_{\mathrm{s}}^{+} $$ → π + π 0 η′

open access: yesJournal of High Energy Physics, 2022
Using data collected with the BESIII detector in e + e − collisions at center-of-mass energies between 4.178 and 4.226 GeV and corresponding to 6.32 fb −1 of integrated luminosity, we report the amplitude analysis and branching-fraction measurement of ...

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

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

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 ...

Strength through diversity: how cancers thrive when clones cooperate

open access: yesMolecular Oncology, EarlyView.
Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.

Measurement of tau lepton branching fractions [PDF]

open access: yes, 1993
We present {tau}{sup {minus}} lepton branching fraction measurements based on data from the TPC/Two-Gamma detector at PEP. Using a sample of{tau}{sup {minus}} {yields} {nu}{sub {tau}}K{sup {minus}}{pi}{sup +}{pi}{sup {minus}} events, we examine the resonance structure of the K{sup {minus}}{pi}{sup +}{pi}{sup {minus}} system and obtain the first ...

Branching fractions in singly ionized tungsten [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2011
The intensity-calibrated spectra of W II have been recorded in the spectral interval 23 000-51 300 cm(-1) (1950-4350 angstrom), using the FT500 UV Fourier Transform Spectrometer at Lund Observatory. Combining the intensity data in this work with lifetimes previously measured using the time-resolved laser-induced-fluorescence (TR-LIF) technique resulted
