Modern Aspects of Nuclear Physics

This course gives a selected overview of aspects in nuclear physics that
came to the forefront of active research within the recent 5 - 10 years.
Substantial progress made in various subfields is discussed in detail. The
target audience are master students in their first or second year that are
interested in the field. This course serves as an entry point for active research
in nuclear and high-energy heavy ion physics, e.g. by starting a master
thesis, and is divided into three parts.
Part 1 covers static properties of the nucleon, e.g. its quark and gluon
structure. Special emphasis is given to the latest insight into the structure of
the nucleon, where results from elastic electron scattering and laser
spectroscopy of the hydrogen hyper-fine structure led to contradicting results.
The newest relevant experiments leading to the resolution of this proton
radius puzzle are discussed. Another aspect is the distribution of partons
inside the nucleon and nuclei. Novel effects might lead to a saturation of the
gluon density inside the nucleon and heavy nuclei. Planned experiments at
the CERN Large Hadron Collider as well as at the Electron-Ion Collider that is
presently being constructed at Brookhaven National Laboratory (BNL) will
shed light on this fundamental issue.
Part 2 addresses the structure of nuclei in extremis, i.e. at largest neutron
numbers until the drip line and beyond. Latest results from experiment and
theory on how to understand the synthesis of nuclei as heavy as uranium and
beyond are discussed. Supernova explosions and the merging of pairs of
neutron stars play a key role in understanding the heavy element production
in the universe. A new window in (nuclear) astrophysics was opened with the
first observation of gravitational waves GW170817 by the LIGO and Virgo
collaborations, where the merging of a neutron star binary was observed.
This promises insight into the equation of state of dense nuclear matter and
progress towards a complete understanding of nuclear abundances in the
Part 3 discusses key developments in relativistic nuclear collisions where
conditions of the early universe, ranging from a few picoseconds to a few
microseconds after the big bang, are investigated in the laboratory. The
CERN Large Hadron Collider (LHC) is the flagship that is operating since ten
years. Abundances of hadrons that are created during the quark-gluon to
hadron phase transition can be understood to good precision within a thermal
model description, leading to an understanding of the quark-hadron phase
transition. Transport observables such as the shear-viscosity-to-entropydensity
ratio reach a universal quantum limit. This limit can be derived from
an AdS/CFT correspondence principle and is thus related to string theory.
Charmonium (charm-anticharm bound states) and multi-charm hadron
production is a harbinger of deconfinement. Recent key results from the LHC
and BNL RHIC collaborations are discussed and confronted with theory.
