Experimental High Energy Physics

The High Energy Experimental Physics area stands out for being one of the pioneers in Chile in the study of the understanding of fundamental forces and the particles of the Universe through experimentation. Much of the research and work carried out by this Group are collaborations linked to world-class centers such as CERN in Switzerland, Jefferson Laboratory and Fermi Laboratory (Fermilab) in the United States.

Research projects

Deep Underground Neutrino Experiment (DUNE)

DUNE will consist of two neutrino detectors positioned in the world's most intense neutrino beam. A detector will record particle interactions near the source of the beam, at the Fermi National Accelerator Laboratory in Batavia, Illinois. A second, much larger detector will be installed more than a kilometer underground at the Sanford Underground Research Laboratory in Lead, South Dakota, 1,300 kilometers downstream from the source. These detectors will allow scientists to search for new subatomic phenomena and potentially transform our understanding of neutrinos and their role in the universe.

Collaboration in ATLAS, CERN

A Toroidal LHC Apparatus (ATLAS) is a unique experiment at the Large Hadron Collider at CERN in Switzerland, investigating new discoveries at the forefront of extraordinarily high-energy proton collisions. With ATLAS you can learn about the basic forces that have shaped our Universe since the beginning of time and that will determine its destiny.

CCTVal has actively collaborated in the update process called ATLAS Upgrade, in which the High Energy Experimental Physics area participates with the modeling, manufacturing and assembly of detectors called small-strip Thin Gap Chambers (sTGC) that fulfill the function muon tracking precision to be located on the Small Wheel (9 meters in diameter). Each sTGC detector has a trapezoidal shape that measures about 1.2 meters long by 1.2 base and 6 millimeters thick and Chile is one of the 5 countries that will manufacture the detectors.

Collaboration in MINERvA, Fermilab

Main Injector Experiment for v-A or MINVERvA, is a neutrino scattering experiment using the NuMI beam from the American laboratory Fermilab. MINVERvA aims to measure the low interaction energy of neutrinos both in support of neutrino oscillation experiments and also to study the strong dynamics of nucleons and nuclei that affect these interactions.

Collaboration at GlueX, Jefferson Lab

GlueX is an experiment that takes place in Hall D of the Jefferson Lab, located in the United States. The objective of the experiment is to acquire important data to meet one of the most fundamental challenges in Physics: the quantitative understanding of the confinement of quarks and gluons in Quantum Chromodynamics (QCD).

CLAS Collaboration, Jefferson Lab

CEBAF Large Acceptance Spectrometer (CLAS) is a detector for nuclear and particle physics studies located in Room B of Jefferson Lab in the United States. It is used to study the properties of nuclear matter through different collaborations of more than 150 physicists (CLAS Collaboration).

CCTVal has collaborated with:

Experiments based on EG2El, which is dedicated to the study of the hadronization process through profoundly inelastic and semi-inclusive arrangements of electrons in the targets of the nucleus of different types (Deuterium, Carbon, Iron, Lead). Such states open the way to demystify the confinement phenomenon in QCD.

Two photon exchange experiment, dedicated to the contribution of the study of the interaction process of electrons with nucleons in which the exchange of two virtual photons occurs, applying calculations of structural functions of nucleons.

Software development for CLAS12, through the CLARA software system for the reconstruction of inventions and data analysis for the operation of the new CLAS12 detector and through electronic hardware projects specific to the experiment.

Collaboration at EIC, Brookhaven National Laboratory

The Electron and Ion Collider (EIC), is a powerful infrastructure that is being created by 100 physicists from laboratories and universities from different parts of the world, which is intended to be built in the United States.

The CCTVal developed and designed a pre-shower detector for electromagnetic rain calorimeters, capable of differentiating between isolated gamma particles and pairs of gamma particles resulting from the decay of neutral pions, all generated in the collision of a high-energy electron beam with a target of ions in a process called DVCS (Deeply Virtual Compton Scattering).

For this, a technology based on a matrix of small flashing crystals (crystals capable of generating light when traversed by charged particles, such as electrons and positrons) is used, together with fiber optics and silicon photomultipliers or MPPC's, for later reading. electronically. With the use of this matrix, it is possible to accurately distinguish the transverse spatial position in which the particles generated in the collision affect. By locating this detector between the point of collision of the particle beam and an electromagnetic rain detector, it is possible to obtain the necessary information to recognize the type of particle incident on the detectors.

Collaboration RD51, CERN

CERN 322USM is a member of CERN's RD51 Research and Development collaboration. This collaboration aims to facilitate the development of a gas avalanche detector technology (or micropattern gas) and an advanced electronic reading system associated with it, for applications in basic and applied research. The main objective of the program is to advance in the technological development and application of micropattern gas detectors.

NASA Project

Together with Jefferson Laboratory, CCTVal participates in the development of highly scalable software that allows processing massive amounts of satellite data captured by the National Aeronautics and Space Administration (NASA), applying modern distributed computing standards. This project originated from JLab, in which CCTVal participated by developing software for physical experimental events of its CLAS12 detector, in which the electrical signals of this particle detector are processed.
