distribution of CTEQ5L the chance of getting a collision of two partons of similar momentum is more probable, hence resulting in a larger probability that the resulting jets be contained within the acceptance. 

The bulk sphericity distributions of several parameters exhibit marked dependence on the gluon PDF used for the computation. As the PDFs for low x$_{B}$ have a larger uncertainty we believe that the present results point to a possibility to further refine gluon PDFs at low x$_{B}$ using the approach presented. In the course of this work we have also tried to check the dependence of the parameters on different fragmentation functions used. The results however do not demonstrate a similar depen- dence as for the PDFs. As one can expect, varying the fragmentation functions one affects slightly the absolute
