Dr J. W. Ballantyne

W. G. J. Hampson

Lady Manners School Bakewell, Corpus Christi College, Oxford, and St. Mary's Hospital. He graduated B.A. (Physiology) in 1960 and M.A., B.M., B.Ch., in 1964. After qualification his first appointment was to the orthopaedic unit at St. Mary's and this post produced a life-long enthusiasm for the speciality. Further posts at St. Mary's followed and he worked at Coventry, Oxford, Liverpool and Edi...

Multiple Parton Interactions in Z + 4 j , W ± W ± + 0 / 2 j and W + W − + 2 j production at the LHC

W. J. Hill, M.R.C.S., L.R.C.P.

Clevedon has lost a good friend and skilful practitioner by the death of Walter Hill on June 2nd, while to his former colleagues at the Bristol Royal Infirmary his untimely and unexpected death at the age of 53 makes a deeply-deplored gap in the alumni of the Bristol School, where he entered as a student in 1880, subsequently taking his M.R.C.S. and L.R.C.P. Remarkable for his quiet, almost ret...

Supersymmetric T-j Models

In this work, we have studied the invariants of motion of two SU (N) super-symmetric t-J models of 1/r 2 hopping and exchange in one dimension. The first model is defined on a lattice of equal spaced sites, and the second on a non-equal spacing lattice. Using the " exchange operator formalism " , we are able to construct all the invariants for the models, by mapping the systems to mixtures of f...
