This proceedings is the fifth in the series of Latin American symposiums focusing on the development, refinement and applications of high energy physics. As the principal meetings for the physics community in Latin America, it encourages collaborations and the exchange of ideas with the international physics communities. This particular symposium was also a dedication to the memory of Dr Luis Masperi.
