Query: News from strong interactions program of the NA61/SHINE experiment   The NA61/SHINE experiment aims to discover the critical point of strongly
interacting matter and study the properties of the onset of deconfinement. This
is performed by a two dimensional phase diagram ($T-\mu_B$) scan of
measurements of particle spectra and fluctuations in proton-proton,
proton-nucleus and nucleus-nucleus interactions as a function of collision
energy and system size.
  In this contribution new NA61/SHINE results on negative pion production, as
well as transverse momentum and multiplicity fluctuations in Ar+Sc collisions
are presented. Moreover, the latest results on higher order moments of
net-charge multiplicity distribution in p+p collisions are also discussed. The
Ar+Sc results are compared to NA61 p+p and Be+Be data, as well as to NA49 $A+A$
results.
