Sumario:In this project work, fragmentation function, jet shapes for hard particles and jet shapes for soft particles have been calculated in different $P_{t}$ range using Pythia Monte-Carlo Simulation at $\sqrt{s}=7$ TeV. For Jet reconstruction, anti-$k_{t}$ algorithm has been used with jet resolution parameter R=0.6 and with momentum cut of particles at 4 GeV. Pseudorapidity was taken to be $|\eta| <2.8 $. The effects of $P_{t}$ cut on the jet shapes of soft particles ($P_t < 4$ GeV) and hard particles ($P_t > 4$ GeV) have been studied. For verification of the working procedure, jet shape for all particles were also calculated with no transverse momentum cut during jet reconstruction and the results were compared to the results of ATLAS measurements. Statistical errors were computed and is well-matched with the order of error with ATLAS measurements.
