Relaxation processes and reaction kinetics of proteins deviate from exponential behavior because of their large amount of conformational substrates. The dynamics are governed by many time scales and, therefore, the decay of the relaxation function or reactant concentration is slower than exponential. Applying the idea of self-similar dynamics, we derive a(More)
We consider the two–nucleon system at next-to-next-to-next-to-leading order (N 3 LO) in chiral effective field theory. The two–nucleon potential at N 3 LO consists of one-, two-and three-pion exchanges and a set of contact interactions with zero, two and four derivatives. In addition, one has to take into account various isospin–breaking and relativistic(More)
The Faddeev equation for three-body scattering below the three-body breakup threshold is directly solved without employing a partial wave decomposition. In the simplest form it is a three-dimensional integral equation in four variables. From its solution the scattering amplitude is obtained as function of vector Jacobi momenta. Based on Malfliet-Tjon type(More)
Relativistic Faddeev equations for three-body scattering are solved at arbitrary energies in terms of momentum vectors without employing a partial wave decomposition. Relativistic invariance is incorporated withing the framework of Poincaré invariant quantum mechanics. Based on a Malfliet-Tjon interaction, observables for elastic and breakup scattering are(More)
The two-body t-matrix is calculated directly as function of two vector mo-menta for different Malfliet-Tjon type potentials. At a few hundred MeV projectile energy the total amplitude is quite a smooth function showing only a strong peak in forward direction. In contrast the corresponding partial wave contributions, whose number increases with increasing(More)
We employ the chiral nucleon–nucleon potential derived in ref.[1] to study bound and scattering states in the two–nucleon system. At next–to–leading order, this potential is the sum of renor-malized one–pion and two–pion exchange and contact interactions. At next–to–next–to-leading order, we have additional chiral two–pion exchange with low–energy constants(More)
The Faddeev equations for the three body bound state are solved directly as three dimensional integral equation without employing partial wave decomposition. The numerical stability of the algorithm is demonstrated. The three body binding energy is calculated for Malfliet-Tjon type potentials and compared with results obtained from calculations based on(More)
The π-mesonic decay of the hypertriton is calculated based on a hypertriton wavefunction and 3N scattering states, which are rigorous solutions of 3-body Faddeev equations using realistic NN and hyperon-nucleon interactions. The total π-mesonic decay rate is found to be 92% of the free Λ decay rate, which is close to the experimental data. Together with the(More)
Developments in spin-polarized internal targets for storage rings have permitted measurements of 197 MeV polarized protons scattering from vector polarized deuterons. This work presents measurements of the polarization observables A(y), iT11, and C(y,y) in proton-deuteron elastic scattering. When compared to calculations with and without three-nucleon(More)
