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

Physics 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 ...

Observation of the semileptonic decay B + → p p ¯ μ + ν μ $$ {B}^{+}\to p\overline{p}{\mu}^{+}{\nu}_{\mu } $$

Journal of High Energy Physics, 2020
The Cabibbo-suppressed semileptonic decay B + → p p ¯ μ + ν μ $$ {B}^{+}\to p\overline{p}{\mu}^{+}{\nu}_{\mu } $$ is observed for the first time using a sample of pp collisions corresponding to an integrated luminosity of 1.0, 2.0 and 1.7 fb −1 at centre-

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

EPJ 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.

Measurement of the branching fraction for ψ(3770)→γχc0

Physics Letters B, 2016
By analyzing a data set of 2.92 fb−1 of e+e− collision data taken at s=3.773 GeV and 106.41×106 ψ(3686) decays taken at s=3.686 GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the partial decay width for ψ(3770)→

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

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

, 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 ...

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

Physics 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-

Measurement of $\mathcal B(\psi(3770)\to\gamma \chi_{c1})$ and search for $\psi(3770)\to\gamma \chi_{c2}$

, 2015
We report a measurement of the branching fraction of $\psi(3770)\to\gamma\chi_{c1}$ and search for the transition $\psi(3770)\rightarrow \gamma \chi_{c2}$ based on 2.92~fb$^{-1}$ of $e^+e^-$ data accumulated at $\sqrt{s}=3.773$~GeV with the BESIII ...
