Sound velocity, equation of state and strangeness in neutron star matter
This presentation in two parts starts with a brief review on the speed of sound in neutron star matter as inferred from observational data. It is pointed out that, in view the strong constraints…

Radiative Corrections and the Renormalization Group for the Two-Nucleon Interaction in Effective Field Theory
We use a combination of effective field theory and the renormalization group to determine the impact of radiative corrections on the nucleon-nucleon potential and the binding energy of the deuteron.…

Production properties of deuterons, helions and tritons via an analytical nucleon coalescence method in Pb-Pb collisions at sNN=2.76 TeV
We improve a nucleon coalescence model to include the coordinate-momentum correlation in nucleon joint distributions, and apply it to Pb-Pb collisions at sNN=2.76 TeV to study production…
