If the linking method has been understood, the properties of such partons can be known. In this study different algorithms that used to reconstruct jets will be presented and compared, k , Cambridge/Aachen and anti-k , Iterative cones in addition t t to the SISCone method, after the comparison found that is the best algorithm is the anti-k algorithm whereas t the Cambridge/Aachen method is the best way to study the substructures of jets.
