Measurement of thermal properties of the LHCb VELO detector using track-based software alignment

The LHCb VELO group

The thermal properties of the LHCb Vertex Locator (VELO) are studied using the real-time detector alignment procedure. The variation of the position and orientation of the detector…

Observation of two resonances in the $Λ_{b}^{0} π^{\pm}$ systems and precise measurement of $Σ_{b}^{\pm}$ and $Σ_{b}^{*\pm}$ properties

LHCb collaboration, R. Aaij, C. Abellán Beteta +837

The first observation of two structures consistent with resonances in the final states $Λ_{b}^{0} π^{-}$ and $Λ_{b}^{0} π^{+}$ is reported using samples of $pp$ collision data collected by the…

Mapping the material in the LHCb vertex locator using secondary hadronic interactions

M. Alexander, W. Barter, A. Bay +63

Precise knowledge of the location of the material in the LHCb vertex locator (VELO) is essential to reducing background in searches for long-lived exotic particles, and in identify…
