High-energy physics, also known as particle physics, is the area of physics that best exemplifies the themes of fundamental physics, such as explaining every observation at its most fundamental level. Seeking new discoveries from the tiniest particles to the furthest reaches of space, High Energy Physics (HEP) investigates what the world is composed of and how it functions at the smallest and largest scales. This goal motivates young people, develops a skilled workforce, and spurs innovation that benefits the country’s health, prosperity, and security.

The objective of high-energy physics is to figure out what the most fundamental building elements of matter are and how these particles interact.

Practical applications

All physics (and the practical applications that result from it) may theoretically be drawn from the study of basic particles. Even if “particle physics” is interpreted to imply merely “high-energy atom smashers,” various technologies have been invented during these pioneering studies that have now found widespread application in society. Particle accelerators are used to make medical isotopes for research and treatment (for example, isotopes used in PET imaging) or to provide external beam radiation directly. The usage of superconductors in particle physics has accelerated their development. CERN was the birthplace of the World Wide Web and touchscreen technology as well. Additional applications with contributions from particle physics may be found in medical, national security, industry, computers, science, and workforce development, demonstrating a long and expanding list of useful practical uses.

Career prospects

Because the discipline involves researching the fundamental components of matter and radiation, HEP careers are always academic or pure research roles. This degree of scientific knowledge has limited practical applicability. Quantum field theory, gauge theory, and the Higgs mechanism are all required for jobs in experimental or theoretical research in this subject. The quantum particles include electrons, neutrino, quarks, bosons, and muons.

A career in high-energy physics aims to discover what physics is beyond our current understanding of the Standard Model. The quest for the Higgs boson, dark matter, and a unified field theory are all areas of research that might lead to a new physics. High-energy colliders aren’t used for every experiment. There are positions available in programmes and laboratories that research cosmic rays and solar radiation from space. Particle physicists can, of course, pursue careers at universities and graduate institutions. Many of these professions entail working in laboratories with high-energy collision facilities.

How to make a career in high-energy physics

To start the career path to become one, you need to first pass intermediate in the science stream. A bachelor’s degree in physics or related subject is necessary to begin with. To specialize, you then need to go ahead and pursue a master’s or doctorate degree in high-energy physics.
