Although no B-factory has yet to observe this decay, the existing measurements provide an important limit on the first inverse momentum $\\lambda_{\\mathrm{B}}$ of the light-cone distribution amplitude (LCDA) of the B-meson. This thesis presents a simultaneous analysis of $B^+ \\to \\ell^+ \\nu_{\\ell} \\gamma$ and $B^+ \\to \\pi^0 \\ell^+ \\nu_{\\ell}$ decays with the Full Event Interpretation tagging algorithm. The analysis is validated with a Belle II data set according to an integrated luminosity of $\\mathcal{L}=63.25 fb^{-1}$.</p>", "headline": "Search for the Rare Decay $B^+ \\to \\ell^+ \\nu_{\\ell} \\gamma$ with the Full Event Interpretation at the Belle II Experiment", "image": "https://publish.etp.kit.edu/static/img/logos/zenodo-gradient-round.svg", "inLanguage": { "@type": "Language", "alternateName": "eng", "name": "English" }, "keywords": [], "name": "Search for the Rare Decay $B^+ \\to \\ell^+ \\nu_{\\ell} \\gamma$ with the Full Event Interpretation at the Belle II Experiment", "url": "https://publish.etp.kit.edu/record/22099" }
