Estimate of material effects on neutral charm mixing at the LHCb experiment — •Lennart Uecker¹, Adam Davis², Evelina Mihova Gersabeck², and Marco Gersabeck² — ¹Physikalisches Institut, Universität Heidelberg, Germany — ²Department of Physics and Astronomy, The University of Manchester, United Kingdom

The LHCb experiment at the LHC is leading the precision measurements in the charm sector. The large charm production cross section and the unique vertex detector, with first detector compoments as close as 6mm to the interaction point, enable the LHCb experiment to measure a larger number of D⁰ mesons passing through material

In this talk, we present a data-driven approach to estimate material effects on the mixing of neutral charm mesons using D⁰ → K π decays recorded during Run 2 of the LHC, corresponding to an integrated luminosity of 5.6 fb⁻¹. Further, we explore the sensitivity of the upgraded LHCb detector for Run 3+4 to material effects on the charm mixing.
