High precision reactor neutrino programm at APC

Final Report Summary - REACTNUTHETA13APC (High precision reactor neutrino programm at APC)

The ReactNuTheta13APC (302309) IEF project was conceived and tailored by the fellow (Pau NOVELLA) and host (Anatael CABRERA, CNRS, APC Laboratory, Paris) to allow the fellow leading participation in state of the art neutrino fundamental research, for the measurement of the θ13 mixing angle of the PMNS leptonics mixing matrix of the Standard Model of Particle Physics. The project was embedded within the flow of the Double Chooz (DC) experiment at the critical stage of transition between the phase-I (single-detector) and phase-II (double-detector) to maximise the impact of the fellow in critical publications (lead a few) and participating the in culminating effort of the construction of a leading neutrino detector, operation led, in many ways, by the host institution. The main operations expected had four sub-projects:

1) Development of the online system of the DC near detector

2) Neutrino oscillation analysis with DC Phase I (single detector)

3) Installation and commissioning of the DC near detector

4) Neutrino oscillation analysis in DC Phase II (double detector)

following two categories: “detector preparation & commissioning” [1,3] and "physics data analysis & publications” [2,4]. They are listed separately to emphasise the timeline logic of the schedule to be followed, although some overlap of sub-projects was expected and realised.

The fellow has performed outstandingly well within the project propose, this becoming one of the top leading physicists of the DC experiment and key physicist in the field. As specific outcome of the project the fellow has realised the following activities:

•led several publication of DC

•participated in world leading conferences in the field with leading results, in a few cases the collaboration entrusted him the release of first results, thanks to his major contribution, or direct leading, of the results

•led one publication (outside the DC framework) of dedicated studies in small sub-collaboration, including host leading members (publication expected by end of 2014, finalising now)

•participated in low level preparation and understanding of detector related issues (calibration, electronics, online) whose output has been critical for the control of detector response systematics

•participated actively in the effective supervision of 3 PhD students and several undergraduate students, member of the host research team

•has become a well know and visible reactor neutrino oscillation expert, recognised by several invitations for seminars and discussion on the field in leading institutions

Finally, given the above highlighted outcome, the fellow, not surprisingly, has been offered a “tenure track” position in one of the leading institutions of neutrino research in the world: IFIC laboratory (Valencia, Spain).
