# Measurement of charged jet cross sections and jet shapes in proton-proton collisions at sqrt(s) = 2.76 TeV with the ALICE detector at LHC

## TL;DR

This paper reports measurements of charged jet cross sections and jet shapes in proton-proton collisions at 2.76 TeV, comparing results with various theoretical models and previous measurements at 7 TeV.

## Contribution

First measurements of charged jet cross sections and shapes at 2.76 TeV with detailed comparison to multiple event generators.

## Key findings

- Jet cross sections are consistent with certain PYTHIA tunes.
- Jet shape observables show agreement with HERWIG and PYTHIA models.
- Results provide baseline data for heavy-ion collision studies.

## Abstract

We present measurements of charged jet cross sections and jet shape observables in leading jet in proton-proton (pp) collisions at sqrt(s) = 2.76 TeV with the ALICE detector at LHC. Jets are reconstructed at the midrapidity from charged particle using sequential recombination anti-kT jet finding algorithm for various R values. The results are compared to measurements from HERWIG, PHOJET and different tunes of PYTHIA6 and earlier measurements at 7 TeV.
