WebbMy research interests have been the phenomenology of elementary particle physics, with particular emphasis on analyses using models that incorporate as much firm general physical theory as possible and the extraction of reliable information from data.

WebbThe arrival of I. Antoniadis to the Particle Physics group brought happily the future of this group in the direction of the particle physics beyond the Standard Model. He has deveveloped a group of String Theory which eventually splitted from the Particle Physics group. T. N. Pham was nominated in 2013 by Phys. Rev. and Phys. Rev. WebbAnyway, back to the first early attempts, and what was observed—it turned out that in scattering at low but relativistic energies, sometimes more particles came out than went in—particles called pions, π+ , π0 , π- were created. The π0 is electrically neutral, the π+ has exactly the same amount of charge as the proton. differentiate a compiler from an interpreter

The ∆++ baryon can be produced as a resonance by aiming a pion beam onto a hydrogen target to produce the reaction π+p → ∆++ → π+p. Calculate the energy and momentum of the pions in the ∆++ centre-of-mass frame. We need the masses of the particles, from the particle properties sheet: m π = 139.6 MeV/c2, m p = 938.3 MeV/c2 … WebbRH anti-particle LH particle RH particle LH anti-particle The helicity dependence of the weak interaction parity violation e.g. Valid weak interaction Does not occur Helicity in Pion Decay Prof. M.A. Thomson Michaelmas 2011 306 The decays of charged pions provide a good demonstration of the role of helicity in the weak interaction differentiate active and latent ptb
