Branching fraction measurement of the decay $B^+ \to \psi(2S) \phi(1020) K^+$ / LHCb Collaboration
The branching fraction of the decay $B^+\to \psi(2S)\phi(1020)K^+$, relative to the topologically similar decay $B^+\to J/\psi \phi(1020) K^+$, is measured using proton-proton collision data collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of $9\,\mathrm{fb}^{-1}$.

Recent Results from SND@LHC / Khalikov, Emil V (SINP, Moscow) ; Ursov, Eduard D (Natl. U. Sci. Tech., Moscow ; SINP, Moscow) /SND@LHC Collaboration
The Scattering and Neutrino Detector (SND@LHC) is a compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in a hitherto unexplored pseudorapidity region of $7.2<\eta<8.4$, complementary to all the other experiments at the LHC. The experiment is located 480 m downstream of IP1 in the unused TI18 tunnel. [...]

Measurement of the multiplicity dependence of $\mitΥ$ production ratios in $pp$ collisions at $\sqrt{s}=13$ TeV / LHCb Collaboration
The $\mit{\Upsilon}(\mathrm{2}S)$ and $\mit{\Upsilon}(\mathrm{3}S)$ production cross-sections are measured relative to that of the $\mit{\Upsilon}(\mathrm{1}S)$ meson, as a function of charged-particle multiplicity in proton-proton collisions at a centre-of-mass energy of $13$ TeV. [...]

An integrated flux-symmetric spectrometer-magnet system for the SND@LHC experiment upgrade / SND@LHC Collaboration
The proposed upgrade of the SND@LHC experiment for the High Luminosity phase of the LHC (HL-LHC) will strongly benefit from the presence of a magnetized region, allowing for muon momentum and chargemeasurement. In this paper we describe an iron core magnet system that is partly integrated with the calorimeter and that is designed to respect the strict constraints from the available space in the experimental cavern, power consumption, and field requirements.Semi-analytical tools are introduced to explore the parameter space, in order to define the primary design options. [...]
