Constraining the Higgs portal with antiprotons [PDF]

, 2014
The scalar Higgs portal is a compelling model of dark matter (DM) in which a renormalizable coupling with the Higgs boson provides the connection between the visible world and the dark sector.

Antiproton-catalyzed fusion [PDF]

Hyperfine Interactions, 1995
Because of the potential application to power production, it is important to investigate a wide range of possible means to achieve nuclear fusion, even those that may appear initially to be infeasible. In antiproton catalyzed fusion, the negative antiproton shields the repulsion between the positively charged nuclei of hydrogen isotopes, thus allowing ...

Warme dichte Materie in Natur und Labor: Ein ungewöhnlicher Materiezustand

Physik in unserer Zeit, Volume 56, Issue 4, Page 198-204, July 2025.
Warme dichte Materie rückt immer mehr in den Fokus, nicht nur in der Physik und Astronomie, sondern auch in den Ingenieurswissenschaften und sogar der Politik. Es handelt sich um interessante, aber auch komplizierte Zustände von Materie, die unser Verständnis ihrer Funktionsweise herausfordern.

Design of a detector to study S=−2$S = - 2$ baryon interactions induced by stopped antiproton annihilation [PDF]

EPJ Web of Conferences, 2019
Stopped antiproton annihilation can initiate an effcient chain of reactions to produce Ξ hyperons in recoil free kinematics, suitable for further investigations of ΞN interactions.

High-precision comparison of the antiproton-to-proton charge-to-mass ratio

Nature, 2015
Invariance under the charge, parity, time-reversal (CPT) transformation is one of the fundamental symmetries of the standard model of particle physics.

Measurement of antiproton annihilation on Cu, Ag and Au with emulsion films [PDF]

, 2017
The characteristics of low energy antiproton annihilations on nuclei (e.g. hadronization and product multiplicities) are not well known, and Monte Carlo simulation packages that use different models provide different descriptions of the annihilation ...

Adiabatic Cooling of Antiprotons

Physical Review Letters, 2011
Adiabatic cooling is shown to be a simple and effective method to cool many charged particles in a trap to very low temperatures. Up to 3×10(6) p are cooled to 3.5 K-10(3) times more cold p and a 3 times lower p temperature than previously reported. A second cooling method cools p plasmas via the synchrotron radiation of embedded e(-) (with many fewer ...

Mechanism of Fixed Pattern Noise of Micro‐Channel Plate Focusing on Cross‐Section of Single Channel

Advanced Electronic Materials, Volume 11, Issue 9, June 2025.
The movement of secondary electrons to the phosphor screen after avalanche in microchannel plate (MCP) is influenced by the single channel cross‐sectional shape. The secondary electron beam emitted from MCP channels with different cross‐sectional shapes affects the energy and position upon striking the phosphor screen, directly impacting FPN (Fixed ...

Polarization analysis of p̄ produced in pA collisions [PDF]

EPJ Web of Conferences, 2019
A quite simple procedure for the generation of a polarized antiproton beam could be worked out if antiprotons are produced with some polarization. In order to investigate this possibility measurements of the polarization of produced antiprotons have been

Possibility of cold nuclear compression in antiproton-nucleus collisions

, 2010
We study the dynamical response of the oxygen-16 nucleus to an incident antiproton using the Giessen Boltzmann-Uehling-Uhlenbeck microscopic transport model with relativistic mean fields.
