¿Cómo se descubren los Secretos del Universo?

What are the basic forces that have shaped the Universe since the beginning of time? How can they determine our future?

These are the essential questions that builds the ATLAS experiment at the Large Hadron Collider (LHC) in the laboratory of CERN (CERN) in Geneva, Switzerland.

Physicists recreate conditions immediately after the “Big Bang” universe. They are seeking new discoveries in head-on collisions of protons of extraordinarily high energy. These discoveries will change our view of energy and matter. After the discovery of the Higgs boson, ATLAS experiment data allow a thorough investigation of the properties of boson and the origins of mass.

Global collaboration

To process data 500 trillion collisions in the LHC networks fast and reliable distributed worldwide with facilities for research data processing are required. The day never comes to an end in the ATLAS experiment is a true global work together in which thousands of scientists from more than 177 universities and laboratories around the world participate.

The ARC Centre of Excellence for Particle Physics (CoEPP), based at the University of Melbourne is the main research center of Australia in high energy physics. The Centre is a collaborative research initiative between the University of Melbourne, University of Adelaide, University of Sydney and Monash University.

By working on the ATLAS experiment at the LHC at CERN, researchers CoEPP contributed to the discovery of the Higgs boson in 2012 and provided valuable and essential resources for the system of global computing Grid for the LHC (WLCG, for their acronym in English). The WLCG system comprises 170 computer centers in 42 countries linking grid computing infrastructure at national and international level.

The mission of the WLCG project is to provide global computing resources to store, distribute and analyze 30 petabytes ~ (30 million Gigabytes) of data generated annually by the LHC. The research team CoEPP computer integrates the storage and processing power around the world through distributed computing technology through Tier-2 center of the ATLAS experiment.

“It is a very important physical time. The discovery of the Higgs boson is a milestone in the physics community and a crucial event for human understanding of the basic laws that govern the universe. As they move scientific discoveries, this is at the top next to find a way to split the atom. the Australian research groups have participated in this project for much of the 25 years, “says the director of CoEPP, Professor Geoffrey Taylor.

The role of networks

“The high capacity and reliability of the center was achieved as a direct result of the excellent performance of network connectivity between the Australian Network of Academic Research (AARNet) and Tier-1 center WLCG at TRIUMF (Canada’s national laboratory for Particle and Physics nuclear) through the Trans-Pacific connection AARNet, SXTransPORT. the rate constant transfer data volumes of HEP over 7Gbps between North America and Australia is not something strange, “says Professor Taylor.

AARNet provided connectivity from the CoEPP to the famous WLCG during the commissioning of the LHC and the second start-up in which the demands of computing infrastructure are greater. Taylor argues that the Doctor will be crucial higher bandwidth network in Australia for the CoEPP can continue to make important contributions to the computing capacity needed for physical analysis.

As the CoEPP continues to gain international recognition for Australia in the field of high energy physics, the ability of collaboration and participation in global projects is further based on the network infrastructure that connects Australian researchers and resources the world.
