Description

The NA61/SHINE experiment aims to discover the critical point of strongly interacting matter and study the properties of the onset of deconfinement. These goals are to be achieved by performing a two dimensional phase diagram ($T$-$\mu_B$) scan by measurements of hadron production properties in proton-proton, proton-nucleus and nucleus-nucleus interactions as a function of collision energy and system size. Close to the critical point increase of fluctuations is predicted. In this contribution preliminary results on transverse momentum fluctuations expressed in terms of strongly intensive quantities ($\phi$, $\Sigma$ and $\Delta$) from the p+p and Be+Be energy scans will be presented. The data is fully corrected for experimental biases using the novel fluctuation analysis method. The NA61/SHINE results will be compared with NA49 data on central Pb+Pb collisions and model predictions.
