Recently, after decades of slow progress, numerous facilities worldwide have observed a large number of new hadronic states, some of them with very unusual properties.

Despite this great advance, the nature of many of these states remains...

Computing remains a prominent and challenging element in the data processing scheme of today’s design of future experiments.

Photons and dileptons are pristine probes of the hot and dense medium formed in heavy-ion collisions, since, once produced, they traverse the fireball undistorted. Dilepton invariant-mass spectra are the only known observable which enable a direct access to an in-medium spectral function, in the vector channel. In the vacuum, and at low mass (M<1.5GeV), the vector spectral function is...

The study of the phase diagram of strongly interacting matter is probably the most challenging problem in the filed of heavy-ion collisions. The most prominent feature of the phase diagram is the existence of the deconfinement/chiral transition lines between hadronic and partonic phases.

Cardiac arrhythmias, like atrial fibrillation, are often treated by radiofrequency catheter ablation. Thereby scar tissue is created to isolate the heart’s conduction system from anatomical areas containing misled electrical signals, which generate and sustain the irregular heartbeat. Catheter ablation procedures have a varying success rate and can lead to severe side effects or even death...

The spectroscopy and decays of some of these particles should also be relevant for the PANDA experiment. We present results on the spectrum of charmed baryons with and without strangeness as well as of charmonium states. The spectra were obtained in lattice...

The mass of the nucleus reflects the total energy of this many-body system and thus is a key property for a variety of nuclear structure and fundamental investigations. Modern experimental techniques, like storage ring or Penning-trap mass spectrometry, have pushed in recent years the limits of sensitivity, resolution and accuracy. This has allowed to access exotic species very far from the...

The description of nuclei starting from the constituent nucleons and the realistic interactions among them has been a long-standing goal in nuclear physics.

Main figures of merit for the SiPM-like detectors - SSPM,...

In historic perspective 3D-detectors have greatly advanced particle physics: cloud and bubble chambers, emulsion chambers, spark and streamer chambers have either led to Nobel Prize-worthy discoveries, or their invention itself was rewarded by a Nobel Prize. However, these detectors are read out visually and are thus notoriously slow. In this respect the invention of multi-wire...

Accelerators and Fragment Separators feeding experimental detectors of large scale scientific instruments, require magnets for the guiding their ion beams.

Investigations of the hyperfine splitting (HFS) in highly charged ions can provide tests of quantum electrodynamics (QED) in the strongest electromagnetic field presently avail- able. The simultaneous study of the HFS in H- and Li-like ions is required, since the Bohr- Weisskopf effect, dominating the theoretical uncertainty, is almost cancelled in the specific difference of the HFS values...

Radiative recombination (RR) is one of the basic processes that occurs in laboratory plasma, in collisions of heavy ions with electrons at ion storage rings and EBIT. During the last decades RR of highly charged heavy ions remains the subject of intense theoretical and experimental research (see Ref.[1] and references therein). Radiative recombination is a time-reversed photoionization,...

Compression modes, i.e., Isoscalar Giant Monopole Resonance (ISGMR) and Isoscalar Giant Dipole Resonance (ISGDR) can be studied in exotic nuclei using inelastic scattering in inverse kinematics. Since the spin and isospin of an alpha particle are both equal to zero, the most favourable process to study the isoscalar L=0 (GMR) and L=1 (GDR) modes is the inelastic alpha particle scattering....

The Compressed Baryonic Matter Experiment (CBM) is one of the core experiments of the future FAIR facility at Darmstadt/Germany. The fixed-target experiment will explore the phase diagram of strongly interacting matter in the regime of highest net baryon densities with numerous probes, among them open charm. Open charm reconstruction requires a vacuum compatible Micro Vertex Detector (MVD)...

The fixed target experiment PANDA will use cooled antiproton beams of unprecedented quality that will be available at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt. PANDA includes the Micro Vertex Detector (MVD) [1], as innermost tracker, and in particular it will allow the secondary vertices of short-lived particles to be detected. Due to the forward boost of the...

X- and Y ─ position slit systems will be used as collimator for stopping the unwanted charge states of primary beam and fragments produced at the reaction target of the in-flight Superconducting Fragment Separator (Super-FRS) at the FAIR facility, GSI. In the case of the most frequently used fission reaction of 238U beam at 1.5 GeV/u on 12C target (2.5 g/cm2) , the most abundant charge states...

The TRIGA-SPEC experiment [1] at the research reactor TRIGA Mainz consists of a Penning trap experiment (TRIGA-TRAP) for mass measurement and a collinear laser spectroscopy setup (TRIGA-LASER). These setups are the prototypes for the MATS- and the LASPEC-Experiments at FAIR [2]. It is used for technical developments to improve the sensitivity and accuracy of the techniques. Additionally the...
