Measuring cross-section data for prompt gammas emitted during proton-nucleus collisions
In Radiation Oncology, proton therapy has become an increasingly popular treatment modality due to the superior dose distribution of the proton beam while sparing more surrounding normal healthy tissues and critical organs. This advantage can quickly turn into a disadvantage if there is any …

Hyperon Production in Proton-Nucleus Collisions at 42 GeV Center of Mass Energy
… target experiment HERA-B, which uses the 920 GeV proton beam of the HERA storage ring at DESY. $\Lambda$, $\Xi$ and $\Omega$ hyperons produced in collisions using carbon and tungsten wires as targets were reconstructed. Hyperon ratios are presented for the rapidity range $-1.5 < y < 0.5$ (where …

Measurement of inclusive Lambda / Antilambda hyperon polarisation in proton nucleus collisions at 920 GeV proton beam energy
… of the HERA-B detector at HERA, DESY, using the proton beam of 920 GeV energy to collide with fixed target wires of different materials. A sample of approximately 2900 Lambdas was obtained in a kinematical region of transverse momentum p_t in [0.2,2.2] GeV/c and Feynman variable x_F in …

Rescattering and fluctuations in ultrarelativistic heavy-ion collisions
We study ultra-relativistic heavy-ion collisions using, as far as possible, known physics and simple assumptions. One focus is on the measurable effects of rescattering of produced particles in the colliding nuclei. Two models for proton-nucleus collisions are presented, one built from independent …

Implementation of a Custom Muon High Level Trigger Monitoring System
… the physics of strongly interacting matter in proton-proton, nucleus-nucleus and nucleus-proton or proton-nucleus collisions at ultra high energy densi- ties, where the Quark Gluon Plasma (QGP) is expected to form. The experiment is expected to produce data at very high rates of about 25 …

Measurements of gamma-ray production cross sections of proton beam at energies of 66 to 125 MeV with calcium target
… Primary cosmic rays are composed mainly of protons, alpha particles and nuclei of many heavier elements. Secondary cosmic rays including neutrons, pions, positrons, and muons are created following the interaction of primary cosmic rays with atmo- sphere. A lot of radioisotopes are formed by …

Schwellennahe Erzeugung von Kaonen und Antikaonen in Proton-Kern-Stößen
… wurde die Produktion von K- und pi-Mesonen in Proton-Kern-Kollisionen ("pA") experimentell untersucht. Verschiedene Targetkerne (C, Au), Strahlenergien (1.6, 2.5, 3.5 GeV) und Beobachtungswinkel (32°-64°) ergaben eine reichhaltige Systematik und gestatteten Extrapolationen auf totale …
