Photon Emission from Dense Quark Matter

C. Vogt, R. Rapp, R. Ouyed

Thermal emission rates and mean free paths of photons in a color-flavor locked (CFL) phase of quark matter at high densities and moderate temperatures are evaluated. Our calculatio…

Subprocess Size in Hard Exclusive Scattering

P. Hoyer, J. T. Lenaghan, K. Tuominen +1

The interaction region of hard exclusive hadron scattering can have a large transverse size due to endpoint contributions, where one parton carries most of the hadron momentum. The…

The Handbag Contribution to Two-Photon Annihilation Into Meson Pairs

C. Vogt

We report on the handbag contribution to two-photon annihilation into pion and kaon pairs at large energy and momentum transfer. The underlying physics of the mechanism is outlined…

Two-Photon Annihilation into Baryon-Antibaryon Pairs

M. Diehl, P. Kroll, C. Vogt

We study the handbag contribution to two-photon annihilation into baryon-antibaryon pairs at large energy and momentum transfer. We derive factorization of the process amplitude in…

The handbag contribution to gamma gamma to pi pi and K K

M. Diehl, P. Kroll, C. Vogt

We investigate the soft handbag contribution to two-photon annihilation into pion or kaon pairs at large energy and momentum transfer. The amplitude is expressed as a hard gamma ga…

gamma* gamma(*) to pi transitions and the pion distribution amplitude

Carsten Vogt

We discuss what can be learned about the shape of the pion distribution amplitude from the form factor for gamma* gamma(*) to pi transitions.
