QCD-motivated models for hadrons predict an assortment of "exotic" hadrons that have structures that are more complex then the quark-antiquark mesons and three-quark baryons of the naive quark-parton model. These include pentaquark baryons, the six-quark H-dibaryon, and tetra-quark and glueball mesons. Despite extensive experimental searches, no unambiguous candidates for any of these exotic...

PANDA is a universal modular 4pi detector for both charged particles and photons that will study antiproton-proton and antiproton-nucleus collisions using the high-quality internal antiproton beam of the HESR storage ring at the international FAIR facility. With beam momenta between 1.5~GeV/c and 15~GeV/c a wide range of physics topics from the light up to the multi-strange and charmed hadron...

The study of the antiproton cross section on nuclei at low energies (eV-MeV region) has implications for fundamental cosmology as well as for nuclear physics. On the other hand, the existing data of antinucleon-nucleon (or -nucleus) annihilation cross-sections are confined to energies above approximately 1 MeV. The ASACUSA collaboration at CERN recently measured antiproton annihilation...

We study the pair-production of heavy mesons in proton-antiproton annihilations within a perturbative QCD motivated framework [A.T. Goritschnig, B. Pire and W. Schweiger, Phys.Rev. D87 (2013) 014017]. In particular we investigate pbar p to pbar D^0 D^0 within a double handbag approach, where the hard process ud ubar dbar to cbar c factorizes from soft matrix elements of c q q operators. The...

Hypernuclear research will be one of the main topics addressed by the PANDA experiment at the planned Facility for Antiproton and Ion Research FAIR at Darmstadt (Germany). Thanks to the use of stored antiprotons beams, copious production of double lambda-hypernuclei is expected at the PANDA experiment, which will enable high precision gamma spectroscopy of such nuclei for the first time, and...

At Panda project, they are planning to produce many double Lambda hypernuclei using p-bar beam. Recently, I performed five-body calculation of Be11LL with alpha alpha +n+2Lambda five-body calculation. In the conference, I will report the calculation and mention what is important to study double Lambda hypernuclei. And I also show the four-body calculation of H4LL using Lambda-Lambda -Xi N...

With the study of hadron and meson production in antinucleon-nucleus reactions a broad spectrum of final particle configurations and physics phenomena becomes accessible. The fundamental interactions of the underlying sub-processes are of high interest by itself. The approach is directed towards investigations of non-strange meson production and strangeness channels, ranging from elementary...

One may wonder why is physics at the scale of a fermi still interesting, when the LHC microscope is tuned to a world a thousand times smaller? Confinement means the universe of quarks and gluons (or even squarks and gluinos) can only be glimpsed through a colourless haze of hadrons. This we need to understand. How this world of hadrons, their spectrum, their structure and dynamics, is being...

for the PANDA collaboration. The proton electric and magnetic form factors in the time-like region (TL-FF) could offer a much richer set of information if compared to the one that can be accessed via the space-like form factors (SL-FF), for which several controversial data are present. An independent experimental determination of the TL-FF would allow for: - a global description of the...

In the year 2010 a subgroup of the PANDA Collaboration started with the first Partial Wave Analysis (PWA) activities. The main objective is to develop a powerful, user-friendly and highly modular PWA software package with the ability to provide amplitudes in different formalisms and to support analyses of all physics cases at PANDA and also of data from other hadron spectroscopy...
