My work focuses on the fundamental physics of the Standard Model and beyond.
One of the few experimental hints for physics beyond the Standard
Model comes from the measurement of the anomalous magnetic moment of
the muon. The Muon g-2
Experiment at Fermilab will repeat this measurement with an
upgraded detector and significantly higher statistics, providing a
definitive confirmation (or not!) of this result, and hopefully a
clear indication of new physics.
The Mu3e
experiment will search for the decay μ→eee. This process is
essentially forbidden in the Standard Model, but can be
significantly enhanced by many processes in
beyond-the-Standard-Model theories. Any observation of this decay
will constitute direct evidence for BSM physics; in the absence of
an observation, Mu3e will exclude BSM physics at energy scales far
beyond those directly accessible at the LHC.
At the Tevatron and LHC, I have previously worked on searching for
new physics in unconventional signatures, precision QCD measurements
(including g→bb splitting), Higgs searches, precision
electroweak measurements, cosmic ray physics, and phenomenological
studies based on these results: developing both searches and measurements to be used for testing and
tuning theoretical models, as well as reinterpreting in the light of
new theories.
In 2009 I wrote a
short Les Houches article
on lepton definitions (see Section 14), which sparked an ongoing
debate on born/dressed/bare lepton definitions. It's not every day
you get to redefine the electron!
There are a range of opportunities to carry out research at UCL,
and I am always happy to work with enthusiastic and curious
students.
If you are interested in carrying out a PhD on g-2 or Mu3e,
details on the application process
are here ,
and information on how your studies could be funded can
be found
here .
Most years I also run projects on g-2, Mu3e as part of the
taught MSc
programme in Physics at UCL .
If you are an undergraduate looking for an interesting 4th year
project on g-2 or Mu3e, please get in
