             "Disentangling the soft and hard components of the pp 
interactions"


                címmel tartandó szemináriumára.


Kivonat:



A new method to extract information from the pp data is proposed. The
approach is based on the use of the event structure variables:
sphericity and spherocity, to split the data into enhanced soft and 
hard
processes samples corresponding to events with large and low numbers of
multi-parton interactions, respectively. The present study was 
developed
in the framework of Pythia 8.180 for inelastic pp collisions at sqrt(s)
=7 TeV. As an application of the method, a study of the identified
particle transverse momentum spectra and their ratios; is presented for
soft (isotropic) and hard (jetty-like) events. The flow-like effect on
these observables due to multi-parton interactions and color
reconnection is relevant for soft events suggesting that partons inside
the jet do not feel color reconnection and its flow-like consequences.
