The NIKA2 Sunyaev-Zeldovich Large Program
  The NIKA2 Guaranteed-Time SZ Large Program (LPSZ) is dedicated to the
high-angular resolution SZ mapping of a representative sample of 45 SZ-selected
galaxy clusters drawn from the catalogues of the Planck satellite, or of the
Atacama Cosmology Telescope. The LPSZ sample spans a mass range from $3$ to $11
\times 10^{14} M_{\odot}$ and a redshift range from $0.5$ to $0.9$, extending
to higher redshift and lower mass the previous samples dedicated to the cluster
mass calibration and universal properties estimation. The main goals of the
LPSZ are the measurement of the average radial profile of the ICM pressure up
to $R_{500}$ by combining NIKA2 with Planck or ACT data, and the estimation of
the scaling law between the SZ observable and the mass using NIKA2, XMM-Newton
and Planck/ACT data. Furthermore, combining LPSZ data with existing or
forthcoming public data in lensing, optical/NIR or radio domains, we will build
a consistent picture of the cluster physics and further gain knowledge on the
mass estimate as a function of the cluster morphology and dynamical state.
