Impact of the Coulomb field on charged-pion spectra in few-GeV heavy-ion collisions

J. Adamczewski-Musch, O. Arnold, C. Behnke +124

In nuclear collisions the incident protons generate a Coulomb field which acts on produced charged particles. The impact of these interactions on charged pion transverse-mass and r…

Deep sub-threshold ϕ production and implications for the K+/K- freeze-out in Au+Au collisions

J. Adamczewski-Musch, O. Arnold, C. Behnke +110

We present data on charged kaons (K+-) and ϕ mesons in Au(1.23A GeV)+Au collisions. It is the first simultaneous measurement of K and ϕ mesons in central heavy-ion collisions bel…

Inclusive ee production in collisions of pions with protons and nuclei in the second resonance region of baryons

R. Abou Yassine, J. Adamczewski-Musch, O. Arnold +125

Inclusive ee production has been studied with HADES in + p, + C and reactions, using the GSI pion beam at = 1.49 GeV.…

Centrality determination of Au+Au collisions at 1.23A GeV with HADES

HADES collaboration, J. Adamczewski-Musch, O. Arnold +106

The centrality determination for Au+Au collisions at 1.23A GeV, as measured with HADES at the GSI-SIS18, is described. In order to extract collision geometry related quantities, su…

(1232) Dalitz decay in proton-proton collisions at T=1.25 GeV measured with HADES

J. Adamczewski-Musch, O. Arnold, E. T. Atomssa +114

We report on the investigation of (1232) production and decay in proton-proton collisions at a kinetic energy of 1.25 GeV measured with HADES. Exclusive dilepton decay channels…

CP Studies and Non-Standard Higgs Physics

S. Kraml, E. Accomando, A. G. Akeroyd +163

There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mi…
