On the Compton scattering vertex for massive scalar QED
A. Bashir, Y. Concha-Sanchez, R. Delbourgo +1
We investigate the Compton scattering vertex of charged scalars and photons in scalar quantum electrodynamics (SQED). We carry out its non perturbative construction consistent with…
Integrity bases for local invariants of composite quantum systems
RIA Davis, R Delbourgo, PD Jarvis
Unitary group branchings appropriate to the calculation of local invariants of density matrices of composite quantum systems are formulated using the method of -function plethys…
Amplitude analysis of hadron decays
R Delbourgo, Dongsheng Liu
We provide succinct covariant amplitude decompositions of 2-body weak hadronic decays, with which to compare data, including exclusive rates, helicity amplitudes and polarizations.…
One-loop effective multi-gluon Lagrangian in arbitrary dimensions
E Rodulfo, R Delbourgo
We exhibit the one-loop multi-gluon effective Lagrangian in any dimension for a field theory with a quasilocal background, using the background-field formalism. Specific results, i…
The gauge technique for heavy quarks
R. Delbourgo, D. Liu
It is possible to determine a propapagator for heavy quarks to order 1/m in any covariant gauge, which applies universally to all quarks, by using the gauge technique. The leading…
Strong and Electromagnetic Interactions of Heavy Baryons
R Delbourgo, Dongsheng Liu
It is possible to express all the strong and electromagnetic interactions of ground state hadrons in terms of a single coupling constant and the constituent quark masses, using spi…
