Commissioning and Performance of the LHCb Upstream Tracker

Abstract

The Upstream Tracker is a new, high-precision silicon strip detector installed in the LHCb experiment as part of the overall LHCb Upgrade I project. The detector is an integral part of the tracking system, and plays a crucial role in the reconstruction of charged particles in the new fully software-based trigger. An overview of the Upstream Tracker detector design, its commissioning, and performance are presented.

Search for $C\!P$ violation in $D^+ \to ϕπ^+$ decays

A search for charge-parity ($C\!P$) violation in the Cabibbo-suppressed $D^+ \to ϕπ^+$ decay is presented, using proton-proton collision data corresponding to an integrated luminosity of $6\text{ fb}^{-1}$, collected at a centre-of-mass energy of $13\text{ TeV}$ with the LHCb detector during Run 2. An abundant sample of $D^+ \to K_{\rm S}^0 π^+$ decays is employed to correct for asymmetries arising from the production of the charmed meson and from detection effects associated with the charged pion accompanying the $ϕ$ meson. Asymmetries induced by interference of multiple processes, such as neutral kaon mixing, regeneration of neutral kaons, and interference between the Cabibbo-favoured $D^+ \to \overline{K}^0 π^+$ and the doubly Cabibbo-suppressed $D^+ \to {K}^0 π^+$ decay, are subtracted. The direct $C\!P$ asymmetry in the $D^+ \to ϕπ^+$ decay is measured to be \begin{equation*} a_{C\!P}(D^+ \to ϕπ^+) = \left(0.1 \pm 4.9\text{ (stat)} \pm 2.4\text{ (syst)} \right)\times 10^{-4}. \end{equation*} For the first time at a hadron collider, the modulus of the ratio and the relative strong phase of the $D^+ \to {K}^0 π^+$ to $D^+ \to \overline{ K}^0 π^+$ decay amplitudes are also investigated. Two-dimensional confidence intervals are reported for these parameters.

A High Performance Partial Wave Analysis Framework for Hadron Spectroscopy

Partial wave analysis (PWA) is a key method in hadron physics for extracting the properties of hadronic resonances. As experimental statistics grow, conventional implementations face severe difficulties in both memory usage and speed. We present \texttt{CTPWA}, a high performance PWA framework based on covariant tensor formalism. This framework adopts extensive precomputation and caching mechanisms, as well as fully GPU-based likelihood computation and minimization. With these optimization, the fitting speed is accelerated by two orders of magnitude relative to autograd-based GPU PWA programs, rendering high-statistics partial-wave analysis feasible at high-precision experiments like BESIII.

FCC-μe: High Energy, High Luminosity Muon-Electron Collider & Neutrino Factory at CERN

The concept is presented of making at the FCC-$ee$ (or CEPC) facility $μ^+e^-$ collisions at the centre-of-mass energy between 1 and 2 TeV and the average luminosity above $10^{34}$cm$^{-2}$s$^{-1}$, concurrently to the $e^+e^-$ collisions. First, a concise scientific motivation is given, including the exciting prospect of measurements of the Higgs boson self-interaction, and is followed by a presentation of the FCC-$μe$ layout -- from the source of ultra-cold anti-muons, through the muon booster, to the main muon ring. Basic considerations are also given regarding the machine-detector interface and the performance of the FCC-$μe$ and associated neutrino factory. The paper concludes with an outlook underlying relevance of such anti-muon beams for any future high energy storage ring as well as for neutrino science.
