physics worldPhysicsworld magazine dedicated an article to our recently published papers about directional measurement of Sub-MeV solar neutrinos with Borexino:

Until now, physicists measuring the properties of solar neutrinos have had to make a compromise – either measure the particles’ energy with high precision and sacrifice directional information or pin down direction and settle for inferior energy resolution. But now physicists working on the Borexino neutrino detector in Italy have shown it is possible to make both measurements simultaneously by exploiting the known position of the Sun at any time to work out the trajectory of electrons scattered by incoming low-energy neutrinos. The team says their new technique paves the way for hybrid measurements that could yield fresh insights into the workings of the Sun and nuclear physics more broadly. […]

The research is described in two papers published in Physical Review Letters and Physical Review D.
