Abstract
The main goal of this work is to employ the Monte Carlo Quark Gluon String Model (QGSM) for description of femtoscopic characteristics in pp collisions at RHIC and LHC. It was found that experimental data can be reasonably well described within the pure string model by increasing the string tension by a factor of two with energy rising from √s = 200 GeV to √s = 900 GeV. The double-Gaussian fit reveals the contributions from resonances and directly produced particles.
