Search for the decay h c → π 0 J/ψ

open access: yesJournal of High Energy Physics, 2022
A search for the decay h c → π 0 J/ψ is performed using a sample of hc produced in the reaction e + e − → π + π − h c . The data samples were collected with the BESIII detector at center-of-mass energies between 4.189 and 4.437 GeV, corresponding to a ...

New results on the search for Bs0 → µ+µ− from LHCb

open access: yesEPJ Web of Conferences, 2013
A search for the rare decays Bs0 → µ+µ− and B0 → μ+μ− is performed with the LHCb experiment using 1.1 fb−1 of data collected at √s = 8 TeV and 1.0 fb−1 of data collected at √s = 7 TeV.

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-

Mapping Childhood Cancer Care Services in Oceania: Methodological Lessons From the SIOP Global Mapping Programme

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT The International Paediatric Oncology Society Global Mapping Programme aims to collect data on global paediatric oncology services by continent, with Africa and Latin America completed. This study reports on the methodology and lessons learned for Oceania, a unique continent with resource disparity across countries, multiple small island ...

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

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Fractional Pebbling and Thrifty Branching Programs.

open access: yes, 2009
We study the branching program complexity of the {\em tree evaluation problem}, introduced in \cite{BrCoMcSaWe09} as a candidate for separating \nl\ from\logcfl. The input to the problem is a rooted, balanced $d$-ary tree of height$h$, whose internal nodes are labelled with $d$-ary functions on$[k]=\{1,\ldots,k\}$, and whose leaves are labelled with ...

Measurement of the tau lepton electronic branching fraction

open access: yesPhysical Review Letters, 1992
The tau lepton electron branching fraction has been measured with the CLEO II detector at the Cornell Electron Storage Ring as [ital B][sub [ital e]]=0.1749[plus minus]0.0014[plus minus]0.0022, with the first error statistical and the second systematic.

Observation of the decay B+→ψ(2S)ϕ(1020)K+ in pp collisions at s=8TeV

open access: yesPhysics Letters B, 2017
The decay B+→ψ(2S)ϕ(1020)K+ is observed for the first time using data collected from pp collisions at s=8TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6fb−1.
