Final state interaction effects in mu-capture induced two-body decay of 3He

R. Skibiński, J . Golak, H. Witała +1

The mu-capture process on 3He leading to a neutron, a deuteron and a mu-neutrino in the final state is studied. Three-nucleon Faddeev wave functions for the initial 3He bound and t…

The intrinsic charm contribution to the proton spin

M. V. Polyakov, A. Schaefer, O. V. Teryaev

The charm quark contribution to the first moment of is calculated using a heavy mass expansion of the divergence of the singlet axial current. It is shown to be small.

Interference Phenomena in Electronic Transport Through Chaotic Cavities: An Information-Theoretic Approach

P. A. Mello, H. U. Baranger

We develop a statistical theory describing quantum-mechanical scattering of a particle by a cavity when the geometry is such that the classical dynamics is chaotic. This picture is…

Lifetimes of agents under external stress

Claus O. Wilke, Thomas Martinetz

An exact formula for the distribution of lifetimes in coherent-noise models and related models is derived. For certain stress distributions, this formula can be analytically evalua…

Deformations of Noncompact Complex Curves and Meromorphic Envelopes of Spheres

S. M. Ivashkovich, V. V. Shevchishin

We study the envelopes of meromorphy of neighborhoods of symplectically immersed two-spheres in complex Kähler surfaces using the Gromov's theory of pseudoholomorphic curves. The c…

Off-mass-shell Sudakov-like suppression factor for the fermionic four-point function in QCD

A. I. Karanikas, C. N. Ktorides, N. G. Stefanis +1

We consider a four-point process, associated with a wide-angle elastic scattering of two off-mass-shell spin-1/2 matter particles, in a non-abelian gauge theory. On the basis of a…
