The PANDA experiment is one of the major projects at the upcoming FAIR facility in Darmstadt, Germany. It will study hadron physics by using antiproton-proton and antiproton-nuclear interactions in the momentum range of 1.5 GeV/c to 15 GeV/c with a 4π state-of-the-art detector. The purpose is to learn about fundamental aspects of the strong interaction in the transition region between...

Using the 2010 data set of proton-proton collisions at a centre-of-mass energy of 7 TeV the CMS experiment has performed a wide range of measurements of quarkonia states which are being updated and extended with new data. This talk will summarize the CMS results on the differential cross sections and spin alignment of charmonium and bottomium states and compare them with other measurements and...

Belle experiment at the KEKB factory, originally dedicated to studies of $B$ mesons, was proved to be a great place also for studying charm physics. The QCD motivated measurements of spectroscopy, decays and production of charmed and charmonium states were succesfully performed at Belle and initiated a lot of theoretical work. In particular, recent discoveries of charmonium-like...

Possible modifications of hadron properties in nuclear matter is subject of extensive theoretical and experimental studies. So far experimental approaches have been limited to the light and strange quark sector. With the PANDA detector at the HESR at FAIR it will be possible to extend this kind of studies to the charm sector in antiproton-nucleus collisions. If the momentum of the incident...

The Ds0*(2317) meson which was discovered at BaBar in 2003 has the interesting properties of a surprisingly narrow width and a mass just below the DK threshold. Different theoretical models try to explain the nature of its properties. A precise knowledge of the width is an important criterion to evaluate these models. However, only an upper limit of 3.8 MeV is known so far. A suitable...
