Recent Heavy Flavour Results from ATLAS
Adam Barton (on Behalf of the ATLAS Collaboration) E-mail: adam. edward. barton@cern. ch Lancaster University. Bailrigg, Lancaster LAI 4YW Received January 16, 2022
A wide programme of heavy flavour production studies are performed with the ATLAS detector [1]. This paper covers recent results in measurements of J/' and '(2S) production at high pT at 13 TeV, studies on the production of B±/B± production cross-section and pentaquark searches in A0 ^ J/'pK- are presented as well.
Keywords: Heavy-Flavour.

Recent results on e+ e- annihilation to hadrons below 2 GeV obtained at the SND experiment at the VEPP-2000 collider are presented. In particular, we discuss measurements of the e+e- ^ n+n- and e+ e- ^ nn cross sections, and study of the processes e+e- ^ n+n-n0, K+ K-n0, nn0y, nnY, and pp. Keywords: collider physics, e+e- annihilation, hadrons.
