Multi-channel joint analysis of the exotic charmonium-like state $T_{c c ˉ} (4020)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +692

This paper reports the first multi-channel joint analysis to identify the properties of the exotic charmonium-like state $T_{c c ˉ} (4020)$ via the electron-positron annihilation…

First measurement of the absolute branching fractions of $Σ^{+}$ nonleptonic decays and test of the $Δ I = 1/2$ rule

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Based on $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected by the BESIII detector at the center-of-mass energy $s = 3.097$ GeV, the first absolute measurement of the branc…

Search for resonances decaying to an anomalous jet and a Higgs boson in proton-proton collisions at $s$ = 13 TeV

CMS Collaboration

This paper presents a search for new physics through the process where a new massive particle, X, decays into a Higgs boson and a second particle, Y. The Higgs boson subsequently d…

First exclusive reconstruction of the B $^{+}$ , B $^{ 0}$ , and B $_{s}^{* 0}$ mesons and precise measurement of their masses

CMS Collaboration

Using proton-proton collision data collected by the CMS experiment at $s$ = 13 TeV in 2016 $-$ 2018, corresponding to an integrated luminosity of 140 fb $^{- 1}$ , the first full…

Search for $1^{-+}$ charmonium-like hybrid via $e^{+} e^{-} \to γ η^{(')} η_{c}$ at center-of-mass energies between 4.258 and 4.681 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +688

Using $e^{+} e^{-}$ collision data corresponding to an integrated luminosity of 10.6 fb $^{- 1}$ collected at center-of-mass energies between 4.258 and 4.681 GeV with the BESIII detec…

Search for $J / ψ \to K_{S}^{0} K_{S}^{0}$ and $ψ (3686) \to K_{S}^{0} K_{S}^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +678

Using data samples of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events and $(2712.4 \pm 14.3) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, we sea…
