Alan Douglas Martin FRS (born 4 December 1937) is a British physicist, currently Emeritus Professor of Physics at the University of Durham.
[2] Martin is known for his research in the theory of elementary particles, which includes studies of mesic atoms, kaon physics, pi–pi scattering, hadron spectroscopy and the anomalous magnetic moment of the muon.
His ongoing projects include the determination of the parton distributions of the proton and studies in small x and diffractive physics, which are relevant to the experiments at the Large Hadron Collider.
Quarks and Leptons, co-authored with Francis Halzen, is a standard text around the world.
[4] He was awarded the 2007 Max Born Medal and Prize for his pioneering research in the understanding of the strong interaction, in particular his theoretical work on the internal structure of the proton.
