Within the one-loop approximation of baryon chiral perturbation theory we calculate all one-pion and two-pion exchange contributions to the nucleonnucleon interaction. In fact we construct the elastic NN-scattering amplitude up to and including third order in small momenta. The phase shifts with orbital angular momentum L ≥ 2 and the mixing angles with J ≥… (More)

The transverse momentum and rapidity distributions of net protons and negatively charged hadrons have been measured for minimum bias proton–nucleus and deuteron– gold interactions, as well as central oxygen–gold and sulphur–nucleus collisions at 200 GeV per nucleon. The rapidity density of net protons at midrapidity in central nucleus– nucleus collisions… (More)

Method Fifty elective cardiosurgical patients at the age of 66 ± 10 years undergoing sternotomy between 09/2014 and 11/2014 at the University Hospital Duesseldorf were enrolled in the trial. All patients were randomly assigned to either group TAPE (n = 25), receiving Kinesio taping after discharge from the intensive care unit, or group CONTROL (n = 25)… (More)

Dirac sea effects are perhaps the most interesting characteristic of relativistic many body theory. In nuclear matter e.g. the effective mass of the nucleons and their coupling to the mesons undergo considerable corrections due to vacuum fluctuations [1], [2]. In addition, relativistic many body theory predicts strong corrections of the properties of… (More)

The Dirac-Brueckner approach to the nuclear many-body problem is described. A family of relativistic mesonexchange potentials is used which apply the pseudovector coupling for the interaction of pseudoscalar mesons ( , ) with nucleons. These potentials describe low-energy two-nucleon scattering and the deuteron data accurately. Using these potentials, the… (More)

Dieses Ergebnis und die vorher beschriebenen vergleichenden Untersuchungen weisen darauf hin, daß für die hydratationsabhängigen Konformationsänderungen der DNS in situ die Artspezifität der DNS und der Proteinkomponente im Komplex, die möglichen Artspezifitäten von Konformationseigenschaften des Komplexes und der Wechselwirkungen zwischen DNS und Protein… (More)

We present the measured correlation functions for π+π−, π−π− and π+π+ pairs in central S+Ag collisions at 200 GeV per nucleon. The Gamov function, which has been traditionally used to correct the correlation functions of charged pions for the Coulomb interaction, is found to be inconsistent with all measured correlation functions. Certain problems which… (More)

We show that the s-wave pion-nuclear potential which reproduces the deeply bound pionic states in Pb, recently discovered at GSI, is remarkably close to the one constructed directly from low energy theorems based on chiral symmetry. Converting this information into an effective pion mass we find mπ/mπ ≃ 1.13 in the center of the Pb nucleus, and mπ/mπ ≃ 1.07… (More)
