We study various reactions involving the one-neutron halo nucleus 15C using a single structure model based on Halo EFT. First, we determine the low-energy constants needed in this description of 15C to reproduce both the one-neutron binding energy of 15C ground state and the asymptotic normalization coefficient (ANC) extracted through the analysis of the 14C(d,p)15C transfer reaction at 17.06...

Charm quarks are primarily produced at early stages of ultra-relativistic heavy-ion collisions and can therefore probe the Quark-Gluon Plasma (QGP) throughout its whole evolution. Final-state open-charm hadrons are commonly used to experimentally study the charm quark interaction with the QGP. Thanks to the precise secondary vertex reconstruction provided by the Heavy Flavor Tracker (HFT),...

The development of Radioactive-Ion Beams (RIBs) in the early 80s has enabled the study of exotic nuclei far from stability. Halo nuclei are among the most peculiar structures discovered since then, they have one or two loosely-bound nucleons which tunnel far from the core of the nucleus, causing their matter radius to be much larger than stable nuclei [1]. Their short lifetimes make their...

Starting from the source, through the cavities, to the target and into the spectrometers the electrons at MESA/MAGIX do not have to pass any windows. Just before entering the detection-system one barrier has to be passed, which is unfortunate, but essential to seperate the vacuum in the spectrometers from the counting-gas inside the detector.

A characteristic feature of nuclei lying on the left of the $\beta$-stability path, extremely far away from it, is their high Q$_{\beta^+}$-value. This can result in the population of highly excited - and often unbound - states in the daughter nuclei. As a consequence, it can lead to $\beta$-delayed (multi-) charged-particle emission, being very competitive to deexcitation via $\gamma$...
