The main purpose of the PANDA experiment at the new international
Facility for Antiproton and Ion Research (FAIR) is the high-precision spec-
troscopy of hadrons in the charm quark sector. This requires an excellent
central tracker (CT) which provides an efficient reconstruction of charged
particle trajectories and secondary vertices, high spatial and vertex resoluti-
on (σrφ ∼ 150 μm, σz...

20 Years of Antiprotonic Helium
Poster
The density shift and broadening of E1-transition lines in antiprotonic helium atoms at helium target pressure of 1 bar and temperatures about 6K are of the order of several ppm, same as the leading relativistic and spin corrections [PRL84,2350(2000)], and needed to be taken into account. To reduce the systematic uncertainty of experimental data, the current spectroscopy measurements of...

Other exotic atoms and rare decays
Poster
The cross sections of the elastic, Stark and Coulomb de-excitation
processes in the collisions of muonic hydrogen with hydrogen atom
have been calculated in the close-coupling approach taking into
account both the closed channels and vacuum polarization shifts of
the $ns$ states. In particular, the cross sections of the elastic
$2s-2s$ scattering and Coulomb $2s-1s$ de-excitation...

Strangeness in Matter
Poster
We have constructed effective separable meson-baryon potentials to match
the equivalent chiral amplitudes with the parameters of the model
fitted to the kaonic hydrogen and low energy $K^{-}p$ reactions data [1].
When the $\bar{K}N$ system is submerged in nuclear medium the $\bar{K}N$
scattering amplitude and the final state branching ratios exhibit
a strong energy...

Antihydrogen
Poster
Positrons ($e^+$) for ATRAP antihydrogen studies are provided by a Surko-style room-temperature Penning trap with $N_2$ buffer gas. ($e^+$) emitted in radioactive decay of $^{22}$Na are thermalized in a solid neon moderator. A short section of magnetic guide steers the $e^+$ to the axis of the Penning trap where interactions with $N_2$ molecules cool them into the bottom of the well where a...

Other exotic atoms and rare decays
Poster
The lightest hadronic atoms ( $\pi^{-}p$, $K^{-}p$, etc.) are of
particular interest among the exotic atoms due to their simplest
structure and unique possibility to give access to the fundamental
properties of hadron-nucleon interaction at threshold energy. The
essential distinction of hadronic atoms as compared with muonic hydrogen
is a complex energy shift in the low...

Strangeness in Matter
Poster
One of the central questions in studying the characteristic of nuclear matter for both, experiment and theory, is the presence of in-medium effects which manifest in the change of hadron properties. Strange particles are essential probes to study in-medium effects of hadrons produced in collisions between nuclei at energies close to the respective nucleon-nucleon production thresholds.
The...

Strangeness in Matter
Poster
Kaon interaction with baryonic matter is characterized by a repulsive potential according to common belief. However, the values of the measured potential are not yet consistent with each other [1,2]. We analyze the kaon in-medium behavior employing K0s's identified with the HADES detector in p+p and p+Nb collisions at 3.5 GeV kinetic beam energy. The comparison of the K0s differential cross...

Within the framework of the program of synthesis and study of the properties of the new elements a series of experiments were performed to produce the elements with odd atomic numbers 115 and 117 using of the Dubna gas-filled recoil separator.
First run was undertaken in 2003. In the reaction of the actinide target Am-243 and Ca-48 beam the two new elements with Z = 113 and 115 were...

The aim of the current experiment is to study the K^+ K^- system in medium properties by using the π^- (1.7 GeV/c)+A→K^+ K^-+X reaction. The experiment with a pion beam poses specific requirements to the detectors and therefore the original FOPI setup needed modifications. The new hardware developments for this experiment include a new design of the veto detector. The main function of the...

Strangeness in Matter
Poster
A missing-mass spectra has been studied for the different channel of reactions as: ’p’ (p,$K^0_s$), С (p,$K^0_s$), ‘p’(p,p$K^0_s$), С(p,p$K^0_s$) , ’p’(p, $\Lambda$), C(p, $\Lambda$),’p’(p, $K^+)\Lambda$, C(p,$K^+)\Lambda$ and so on. There are statistically small peaks (3-4 S.D.) which are observed by this method on mass range of $K^0$(498), $\Lambda$(1520), $\phi$(1020), $\Sigma$...

We study the strangeness production at finite temperature and density nuclear matter by means of an effective relativistic mean-field model with the inclusion of the full octet of baryons, the Delta-isobars degrees of freedom and the lightest pseudoscalar and vector mesons. These last particles are considered taking into account of an effective chemical potential and an effective mass...

This experimental data for events with $\Lambda$ hyperons in p+C reaction at 10 GeV/c is compared to the UrQMD model as a first step that there will be one of basis for study of multi strange hyperons and exotica productions with high statistics in heavy nucleus collisions . The experimental data with $\Lambda$ hyperons was used as generator for GEANT -...
