*The Road to Nuclear Physics from Standard Model

*
At the core of nuclear physics is to understand complex phenomena 
occurring in the hottest
and densest known environments in nature, and to unravel the mystery of 
the dark sector and
other new physics possibilities. Nuclear physicists are expected to 
predict, with certainty, the
reaction rates relevant to star evolutions and nuclear energy research, 
and to obtain the “standard”
effects in nuclei to reveal information about the “non-standard” sector. 
To achieve such certainty,
the field has gradually started to eliminate its reliance on the 
phenomenological models and has
entered an era where the underlying interactions are "effectively" based 
on the Standard Model of
particle physics, in particular Quantum Chromodynamics (QCD). The 
few-nucleon systems can
now emerge directly from the quark and gluon degrees of freedom and with 
only QCD interactions
in play, using the numerical method of lattice QCD. Few-body observable, 
such as few-hadron
interactions and scattering amplitudes, as well transition amplitudes 
and reaction rates, have been
the focus of this vastly growing field. Once obtained from QCD, and 
matched to effective field theories,
these can advance and improve the nuclear many-body calculations of 
exceedingly more complex
systems. This talk is a brief introduction to this program and its 
goals, with a great focus on an example
with phenomenological importance to demonstrate the road map described 
above.
