Mexican contribution to ALICE and first data analysis

On November 2009 the Large Hadron Collider produced the first p+p collisions. These, together with the upcoming Pb+Pb data, open up the possibility to answer some of the intriguing questions regarding the Standard Model and likely bring to light new phenomena. In this work I present a short review of the mexican participation in the ALICE experiment, focusing on the detector building and phenemological as well as Monte Carlo simulation work regarding the proton as well as the heavy ion program. I also briefly mention some of the wide spectrum of possible first topics that can be analyzed.
