Moon’s orbit proposed as a gravitational wave detector

March 17, 2022

IFAE Theory Group member Diego Blas, in collaboration with Alexander Jenkins from UCL, propose using the variations in distance between the Earth and the Moon, which can be measured with a precision of less than a centimeter, as a new gravitational wave detector within a frequency range that current devices cannot detect. The research, which could pave the way for the detection of signals from the early universe, was published recently in Physical Review Letters.

New experimental results on the universal lepton flavour observable Q5

December 23, 2016

The results show a deviation with respect to the SM predictions that is not yet statistically significant (2.6 sigma for muons and 1.1 sigma for electrons) but coherent with other measurements of the muonic channel and with other observables pointing to the same type of asymmetry between muons and electrons.
