The Large Hadron Collider beauty (LHCb) detector is designed to detect decays of b- and c- hadrons for the study of CP violation and rare decays. At the end of the LHC Run 2, many of the LHCb measurements remained statistically dominated. [...]

Rogue quantum harmonic oscillations / Bayındır, Cihan (CERN ; Istanbul, Tech. U. ; Bogazici U.)
We show the existence and investigate the dynamics and statistics of rogue oscillations (standing waves) generated in the frame of the nonlinear quantum harmonic oscillator (NQHO), also known as the Gross–Pitaevskii equation (GPE). With this motivation, in this paper we develop a split-step Fourier scheme for the computational analysis of NQHO. [...]

Search for $bb\bar{b}\bar{b}$ tetraquark decays in 4 muons, $B^{+} B^{-}$, $B^0 \bar{B}^0$ and $B_s^0 \bar{B}_s^0$ channels at LHC / Becchi, C. (INFN, Genoa) ; Giachino, A. (INFN, Genoa) ; Maiani, L. (Tsung-Dao Lee Inst., Shanghai ; Rome U. ; INFN, Rome) ; Santopinto, E. (INFN, Genoa)
We perform a quantitative analysis of the $bb\bar{b}\bar{b}$ tetraquark decays into hidden- and open-bottom mesons and calculate, for the first time, the $bb\bar{b}\bar{b}$ tetraquark total decay width. On the basis of our results, we propose the $bb\bar{b}\bar{b} \to B^{+} B^{-} (B^0 \bar{B}^0) (B_s^0 \bar{B}_s^0) \to l^{+} l^{-}+\text{X}$ decays as the most suitable channels to observe the $bb\bar{b}\bar{b}$ tetraquark states, since the calculated two-lepton cross section upper limit, $\simeq 39 $ fb, is so large as to be potentially detectable with the 2018 LHCb sensitivity, paving the way to the observation of the $bb\bar{b}\bar{b}$ tetraquark in the future LHCb upgrade.

Mono-$b$ events from single stop production at the HL-LHC and HE-LHC / Tang, Tian-Peng (Nanjing Normal U.) ; Liu, Ning (Nanjing Normal U.) ; Zhou, Hang (Nanjing Normal U.)
Top-squarks (stop) play an important role in SUSY naturalness. The stop pair production is considered as the most effective way to search for stop at the LHC. [...]

A particle detection system that exploits the scintillation light produced by ionizing particles in liquid argon (LAr) has been assembled at CERN. The system is based on 10 large-area photomultiplier tubes (PMT) immersed in a 1500-liter dewar filled with liquid argon and equipped with an extendible feed-through and mechanical support for an alpha source (241Am).

Construction of precision wire readout planes for the Short-Baseline Near Detector (SBND) / Acciarri, R. (Fermilab) ; Adams, C. (Argonne (main)) ; Andreopoulos, C. (U. Liverpool (main)) ; Asaadi, J.

The Short-Baseline Near Detector time projection chamber is unique in the design of its charge readout planes. These anode plane assemblies (APAs) have been fabricated and assembled to meet strict accuracy and precision requirements: wire spacing of 3 mm +/- 0.5 mm and wire tension of 7 N +/- 1 N across 3,964 wires per APA, and flatness within 0.5 mm over the 4 m +/- 2.5 m extent of each APA.

Prospects for Lorentz-Violation Searches with Top Pair Production at the LHC and Future Colliders / Carle, A. (Lyon, IPN) ; Chanon, N. (Lyon, IPN) ; Perriès, S. (Lyon, IPN)
This article presents prospects for Lorentz-violation searches with $t\bar{t}$ at the LHC and future colliders. After a short presentation of the Standard-Model Extension as a Lorentz-symmetry-breaking effective field theory, we will focus on $t\bar{t}$ production. [...]

Precision timing calorimetry with the CMS HGCAL / Lobanov, Artur (Ecole Polytechnique) /CMS Collaboration
The existing CMS endcap calorimeters will be replaced with a High Granularity Calorimeter (HGCAL) for operation at the High Luminosity (HL) LHC. Radiation hardness and excellent physics performance will be achieved by utilising silicon pad sensors and SiPM-on-scintillator tiles with high longitudinal and transverse segmentation. [...]

Proposal on application of the multi-wire proportional chambers of the LHCb MUON Detector at very high rates for the future upgrades / Bondar, N. (St. Petersburg, INP ; CERN) ; Ilin, D. (St. Petersburg, INP) ; Maev, O. (St. Petersburg, INP)
The MUON Detector (MD) of LHCb is one of the largest instruments of this kind worldwide, and one of the most irradiated. It has performed exceptionally well during the RUN1 and RUN2 of the LHC at an instantaneous luminosity of 4$\times$10$^{32}$ cm$^{-2}$s$^{-1}$, with tracking inefficiencies at the level of 1$\%$ and 2.6$\%$, respectively.
