Motivated by evidence for the existence of dark matter, many new physics models predict the pair production of new particles, followed by the decays into two invisible particles, leading to a momentum imbalance in the visible system. For the cases where all four components of the vector sum of the two "missing" momenta are measured from the momentum imbalance, we present analytic solutions of the final state system in terms of measurable momenta, with the mass shell constraints taken into account. We then introduce new variables which allow the masses involved in the new physics process, including that of the dark matter particles, to be extracted efficiently. These are compared with a selection of variables in the literature, and possible applications at lepton and hadron colliders are discussed.

The latest results on standard candle central exclusive production (CEP) processes within the pQCD based Durham model are discussed, which involve the production of systems with sufficiently low masses that observation of these processes is already possible at the Tevatron and in the early LHC low pile-up runs. The CEP of the χc meson is in particular addressed, concentrating on the χc → π+π-channel. The continuum background to this process is calculated, which requires a careful treatment of both the 'perturbative' and 'non-perturbative' contributions, and is found to be under control once suitable cuts are imposed on the final state pions. The CEP of other meson pairs, such as flavour-singlet states, which have much larger predicted cross sections than in the case of π+π-CEP, is also discussed.
