Towards an amplitude analysis of the decay Λb0→pK−γ Albrecht, Johannes Amhis, Yasmine Beck, Anja Marin Benito, Carla Fenomenologia Quarks Model estàndard (Física nuclear) Phenomenology Quarks Standard model (Nuclear physics) The helicity formalism applied to the radiative decay Λ0 b → pK−γ is presented for the first time in this paper. The aim is to provide the necessary formalism to be able to resolve the resonant pK− structures at the photon pole by means of an amplitude analysis. Experimental effects, such as resolution, are also discussed. 2025-04-10T16:06:23Z 2025-04-10T16:06:23Z 2020 2025-04-10T16:06:24Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1126-6708 https://hdl.handle.net/2445/220397 757909 eng Reproducció del document publicat a: https://doi.org/10.1007/JHEP06(2020)116 Journal of High Energy Physics, 2020, vol. 6, num.116, p. 1-16 https://doi.org/10.1007/JHEP06(2020)116 cc-by (c) Albrecht, J. et al., 2020 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess 16 p. application/pdf Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
