Relations among polarized and unpolarized splitting functions beyond leading order
[DESY-98-070; hep-ph/9806355]
The role of various symmetries in the evaluation of splitting functions and coefficient functions is discussed. The scale invariance in hard processes is known to be a guiding tool to understand the dynamics. [...]

Test of a High Resolution Drift Chamber Prototype
[DESY-84-049]
The performance of a drift chamber prototype for a colliding beam vertex detector in a test beam at DESY is described. At one (two) atmosphere gas pressure a spatial resolution of 40 μm (30 μm) per wire for one cm drift length was achieved with a 100 MHz Flash-ADC system. [...]

WEAK INTERACTIONS: PETRA RESULTS
[DESY-84-048]
Bottom quarks 18 pp. () [10.1063/1.34786]  GO
Recent results on weak interactions from experiments at the PETRA e+e− storage ring are presented. They include the determination of the weak neutral couplings in the purely leptonic reactions e+e−→e+e−, e+e−→μ+μ− and e+e− →τ+τ− and in the production of heavy charm and bottom quarks e+e−→cc̄ and e+e−→bb̄.

Monopole - Fermion and Dyon - Fermion Bound States. 2. Weakly Bound States for the Lowest Angular Momentum
[DESY-84-047]
We investigate weakly bound dyon-fermion states of the lowest angular momentum. Both Coulomb attraction and Coulomb repulsion are studied. [...]
