Search for the Higgs boson decay to a pair of electrons in proton-proton collisions at s=13TeV

open access: yesPhysics Letters B, 2023
A search is presented for the Higgs boson decay to a pair of electrons (Image 1) in proton-proton collisions at s=13TeV. The data set was collected with the CMS experiment at the LHC between 2016 and 2018, corresponding to an integrated luminosity of ...

First measurement of the differential branching fraction and CP asymmetry of the B± → π±μ+μ− decay [PDF]

open access: yesJournal of High Energy Physics, 2015
The differential branching fraction with respect to the dimuon invariant mass squared, and the CP asymmetry of the B± → π±μ+μ− decay are measured for the first time. The CKM matrix elements |Vtd| and |Vts|, and the ratio |Vtd/Vts| are determined.

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 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 ...

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.

Study of Exclusive B decays to Charmed Baryons

open access: yes, 2002
Using 29.1fb-1 of data accumulated at the Upsilon(4S) with the Belle detector at KEKB, we have studied the decay modes B0bar->Lambda_c+ pbar pi+pi-, B- -> Lambda_c+ pbar pi-, and B0bar ->Lambda_c+ pbar. We report branching fractions of exclusive B decays

First observation and measurement of the branching fraction for the decay Bs0 → Ds∗∓K± [PDF]

open access: yes, 2015
A bstractThe first observation of the Bs0 → Ds∗∓K± decay is reported using 3.0 fb−1 of proton-proton collision data collected by the LHCb experiment. The Ds∗∓ mesons are reconstructed through the decay chain Ds∗∓ → γDs∓(K∓K±π∓).

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-

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

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 ...
