Research Interests

I have been involved in a broad range of activities in experimental particle physics research using high energy particle accelerators and colliding beam machines: design, construction, operation and scientific exploitation of particle detectors & experiments at these facilities (including software and computing resources). Most of my career has been devoted to precise tests of the Standard Model of particle physics in both the strong & electroweak sectors and indirect searches for the top quark & the Higgs boson (the key to understanding the origin of mass); more recently drawn to the search for flavour mixing and CP violation in beauty hadrons and neutrinos (the key to understanding the matter-antimatter asymmetry of the universe).

I am currently working on the D-Zero experiment at Fermilab and on the T2K neutrino oscillations experiment in Japan. Previously, I was involved for several years in the design and construction of the ATLAS experiment at CERN’s Large Hadron Collider (LHC). Prior to that I worked for nearly twenty years on a series of electron-positron annihilation experiments at centre of mass energies ranging from 3 Gev (CRYSTAL BALL at SLAC) to 46 GeV (TASSO at DESY) and finally to 200 GeV (DELPHI at LEP). My main physics interest during this period was the study of electroweak interactions. Whilst working on DELPHI I served as the Electroweak Physics coordinator and as a convenor of the Tau Physics team. I wrote my PhD thesis on deep inelastic neutrino scattering with the Gargamelle Bubble Chamber at CERN.

The D-Zero experiment is located at the Fermilab proton-antiproton collider, the Tevatron. Lancaster joined the experiment in the Spring of 1999. We are involved in various physics topics associated with b-quark production and have produced a substantial number of new measurements and observations including the first double-sided limit on Bs mixing, and several searches for CP violation. I have been one of the co-conveners of the Tracking and Vertexing Algorithms group in D-Zero.

The T2K long-baseline neutrino oscillations experiment consists of a low energy neutrino beam produced at the JPARC facility in Tokai, Japan, a Near Detector (ND280) located 280m from the origin of the beam and a Far Detector (SuperKamiokande) positioned 295Km downstream. The key goal of the experiment is to observe the appearance of electron type neutrinos in the muon neutrino beam and hence measure the last of the three neutrino mixing angles (theta_13). In 2011, T2K observed the first indications of electron neutrino appearance, thereby demonstrating that theta_13 is non-zero (at the 3 standard deviations level) and actually quite large (subsequently confirmed by reactor neutrino experiments). The Lancaster group was responsible for building the 6 ton Downstream Electromagnetic Calorimeter module (DSECal), parts of the rest of the calorimeter and various offline software contributions. The current goals of T2K are to improve its measurements of theta_13 and one of the other neutrino mixing angles (theta_23), measure various inclusive and exclusive neutrino interaction cross sections and search for CP violation in neutrino oscillations. I am the ND280 shift coordinator in 2013.
