Impact – Dawn Douglas

the impact

.

With the founding of the IPPP, a joint venture of the University of Durham and PPARC, particle physics phenomenology in the UK has been substantially revived.

The IPPP has had major successes: creating a critical mass of particle theorists in Durham […] reviving particle phenomenology throughout the UK, and the organisation of many meetings and workshops.

This development is very important, since it is essential that UK experimentalists and theorists be ready to exploit discoveries made at the LHC

Second International Review of UK Research in Physics and Astronomy

… wider afield• the increase in phenomenology in Durham since the IPPP

started has stimulated an enormous increase in phenomenology elsewhere in the UK

heavy quark physicsA4

• the laws of physics are almost, but not quite, invariant under CP transformations

• CP violation is believed to be the origin of the matter-antimatter asymmetry in the Universe

• CP violation is built in to the Standard Model (SM), where it is most easily studied in the weak decays of mesons containing heavy quarks, for example at B-Factories

• in the SM, weak transitions between quarks are parametrised by the (complex) “CKM Matrix”

Topics under study at IPPP• problem of strong interaction effects (heavy quarks confined in mesons)

which contaminate weak decay measurements – sum rules, factorisable corrections, distribution amplitudes

• sensitivity of B decays (e.g. B → KS, BS → µµ ) to physics beyond the Standard Model, in particular Supersymmetry and models with “large” extra dimensions

neutrino & astroparticle physicsA5

e

Topics under study• neutrinos – Dirac or Majorana fermions? neutrinoless double beta decay experiments

• neutrino masses and CP violation: superbeams, betabeams, neutrino factory

• models for neutrino mass generation (e.g. “see-saw mechanism”)

• implications for leptogenesis and baryogenesis

• connections with cosmology and astroparticle physics
