Measurements of the coherence factor $R_{K3\pi}$, average strong-phase difference $\delta^{K3\pi}_D$ and mean amplitude ratio $r_D^{K3\pi}$ for decay $D \to K^-\pi^+\pi^+\pi^-$ are presented. These parameters important inputs to determination unitarity triangle angle $\gamma$ in $B^- DK^-$ decays, where $D$ designates a superposition $D^0$ $\bar{D}{}^0$ mesons decaying common final state. The results based on combined fit observables obtained from re-analysis CLEO-c $\psi(3770)$ data set...
Precise knowledge of the location material in LHCb vertex locator (VELO) is essential to reducing background searches for long-lived exotic particles, and identifying jets that originate from beauty charm quarks. Secondary interactions hadrons produced beam-gas collisions are used map VELO. Using this map, along with properties a reconstructed secondary its constituent tracks, $p$-value can be assigned hypothesis originates interaction. A validation procedure presented using photon...
A binning scheme is proposed for $D^0 \to K^+\pi^-\pi^-\pi^+ $ phase space that will improve the sensitivity of a $B^- DK^-$ analysis to angle $\gamma$ Cabibbo-Kobayashi-Maskawa Unitarity Triangle. The makes use amplitude models recently reported by LHCb collaboration. Assuming four-bin optimised on retains similar when applied in data, it estimated statistical uncertainty from $B$-meson sample so far collected experiment be as low 5 degrees. This one most precise results available any...
We performed a detailed study of the timing performance LHCb VELO Timepix3 Telescope with 180 GeV/c mixed hadron beam at CERN SPS. A twofold method was developed to improve resolution single-plane time measurements, resulting in more precise overall track measurement. The first step uses spatial information reconstructed tracks combination measured signal charge sensor correct for mixture different effects: variations carrier drift time; induction, which are result non-uniform weighting...
The Large Hadron Collider beauty (LHCb) detector is designed to detect decays of b- and c- hadrons for the study CP violation rare decays. At end LHC Run 2, many LHCb measurements remained statistically dominated. In order increase trigger yield purely hadronic channels, hardware will be removed, read out at 40 MHz. This, in combination with five-fold luminosity, requires radical changes LHCb's electronics, and, some cases, replacement entire sub-detectors state-of-the-art technologies....
Abstract The spatial and temporal performance of a four-plane system composed silicon sensors bump-bonded to Timepix4 ASICs is assessed with 180 GeV/c mixed hadron beam at the CERN SPS reported in detail. Particle tracks are reconstructed using time-space measurements from four detector planes, two 100 μm planes perpendicular 300 under an angle 9°. hit resolution be (15.5 ± 0.5) (4.5 0.3) for thick sensors, respectively. timestamps detectors also measured fine precision, yielding time...
