Charm electroproduction viewed in the variable-flavour number scheme versus fixed-order perturbation theory
M. Buza, Y. Matiounine, J. Smith +1
Starting from fixed-order perturbation theory (FOPT) we derive expressions for the heavy-flavour components of the deep-inelastic structure functions FL and F2 in the variable-flav…
Monads and D-instantons
Jae-Suk Park
Motivated by twisted N=4 supersymmetric Yang-Mills theory in 4 dimensions, a natural extension of the monad (ADHM) construction relevant to D-instantons is considered. We show that…
Ginzburg-Landau theory of the cluster glass phase
Th. M. Nieuwenhuizen, C. N. A. van Duin
On the basis of a recent field theory for site-disordered spin glasses a Ginzburg-Landau free energy is proposed to describe the low temperatures glassy phase(s) of site-disordered…
Adiabatically changing the phase-space density of a trapped Bose gas
P. W. H. Pinkse, A. Mosk, M. Weidemüller +3
We show that the degeneracy parameter of a trapped Bose gas can be changed adiabatically in a reversible way, both in the Boltzmann regime and in the degenerate Bose regime. We hav…
Monitoring the Gamma-Ray Source 2CG 135+1 and the Radio Star LSI+61 303
M. Tavani, W. Hermsen, R. van Dijk +8
We report the results of a CGRO multi-instrument series of observations of the unidentified gamma-ray source 2CG 135+1 and of its possible counterpart, the peculiar radio source GT…
Prospects for spin physics in semi-inclusive processes
P. J. Mulders
I discuss inclusive and semi-inclusive lepton-hadron scattering emphasizing the importance of polarization in order to study various single or double spin asymmetries and the impor…
