<b>The Low-Energy Frontier of the Standard Model: From Hadrons to
New Physics
</b><br>
<br>
The Standard Model (SM) has been tremendously successful in
explaining all particle physics observations so far. However, there
are strong indications that yet unknown particles and/or
interactions have to exist. The Precision, or Low-Energy frontier of
the Standard Model aims at detecting effects of this New Physics as
deviations from the SM predictions in low-energy observables, and
the precision of measurements and calculations of these observables
is in direct correspondence with the scale at which the New Physics
emerges. This requires understanding the SM at low energies, most
notably the Quantum Chromodynamics (QCD), the theory of strong
interactions. QCD explains the strongly interacting matter and its
properties in terms of quarks and gluons, and it is a complicated
multi-scale problem. The detailed understanding of the QCD in the
non-perturbative regime is lacking, and a joined effort from
Lattice, Effective Field Theories and Phenomenology is necessary. On
the example of the parity-violating electron scattering and light
muonic atoms I will review how state-of-the-art calculations helped
improve the precision of the SM predictions in the kinematics of
running and upcoming experiments, and motivated new dedicated
experiments. <br>
