Fionn C. R. Bishop is a British particle physicist specialising in flavour physics, CP violation, and B meson decays. She is a postdoctoral researcher at the Laboratoire d'Annecy de Physique des Particules (LAPP) in Annecy, France, working on the LHCb experiment at CERN's Large Hadron Collider.[1]
Early life and education
Bishop grew up in Dorset, England, and attended The Thomas Hardye School in Dorchester.[2] While at school, she reached the second round of the British Physics Olympiad, placing in the top 50 out of approximately 2,000 entrants nationally.[2]
In 2015, she matriculated at Murray Edwards College, University of Cambridge, to read Natural Sciences.[3] During her undergraduate studies, she undertook a summer studentship at DESY in Hamburg, Germany, analysing data from the ATLAS experiment at the Large Hadron Collider.[4] This experience sparked her interest in the physics of beauty quarks.
In Autumn 2019, Bishop began her PhD at the Cavendish Laboratory under the supervision of Professor Valerie Gibson, as the inaugural recipient of the P.C. Ho Scholarship, funded by the Huo Family Foundation.[4] Her doctoral thesis, Beauty meson to double open charm decays with the LHCb detector, was completed in April 2023.[5]
Research
Bishop's research focuses on precision measurements of B meson decays involving two charm mesons, using data collected by the LHCb detector at CERN. Her work contributes to tests of the Standard Model and searches for new physics through CP violation studies.
First evidence for B+
c → D+
s D0
Bishop's PhD research included a search for sixteen rare decay modes of the B+
c meson to pairs of charm mesons, using 9 fb−1 of proton–proton collision data. The analysis found the first evidence for the decay B+
c → D+
s D0
, with a statistical significance of 3.4 standard deviations, and measured its branching fraction.[6] The measured branching fraction was noted as being in tension with certain theoretical predictions, potentially indicating either a departure from the current understanding of B+
c meson phenomenology or a contribution from beyond-Standard-Model physics.[1]
CP asymmetry measurements
Bishop performed world-first measurements of charge-parity (CP) asymmetries in double-charm decays of lighter B mesons. Using flavour symmetries to constrain subleading amplitudes, these measurements achieved percent-level sensitivity to potential contributions from new physics.[1][5]
LHCb trigger upgrade
As part of her doctoral work, Bishop also contributed to the development of neural network selections for the upgraded trigger system of the LHCb detector, designed to enable future precision measurements of doubly charmed beauty decays and CP violation studies in the LHCb Upgrade era.[5][7]
Public engagement
In December 2020, Bishop participated in the Cambridge Conversations public lecture series alongside Professors Andy Parker and Valerie Gibson, and Dr Harry Cliff, in a discussion entitled "Beauty and the Beast: Matter, Antimatter and the Large Hadron Collider", exploring the work of the LHCb experiment and the matter–antimatter asymmetry of the universe.[3]
