Large Hadron Collider: Ghost Particles Detected in LHC for the First Time

 

Ghost Particles Detected: Relevance

  • GS 3: Science and Technology- developments and their applications and effects in everyday life.

 

Ghost Particles Detected: Context

  • Recently, for the first time, researchers have detected neutrino candidates produced by the Large Hadron Collider (LHC) at the CERN facility.

 

Ghost Particles Detected: Key points

  • In what could be referred as a major milestone in particle physics, researchers have reported observing six neutrino interactions during an experiment at the LHC.
  • Prior to this project, no sign of neutrinos has ever been seen at any particle collider, and not just at LHC.

Ghost Particles Detected: Significance

  • This significant breakthrough is a step toward developing a deeper understanding of these elusive particles and the role they play in the universe.
  • Detecting collider neutrinos provides access to neutrino energies and types that are rarely seen elsewhere.

 

 

Neutrinos definition

  • Neutrinos are subatomic particles that have a very small mass like an electron. Neutrinos, however, have no electrical charge. This characteristic of neutrinos makes them extremely difficult to detect.
  • Neutrinos are actually everywhere. They’re one of the most abundant subatomic particles in the Universe.
  • As they carry no charge and have almost zero mass, they stream through the Universe at almost the speed of light, and barely interact with it at all.

Ghost particles meaning

  • Billions of the things are streaming through us right now. To a neutrino, the rest of the Universe is basically incorporeal; that’s why they’re also known as ghost particles.

 

LHC working

  • The LHC—which includes four main detectors: ALICE, ATLAS, CMS and LHCb—generally works by colliding two high-energy particle beams with one another close to the speed of light.
  • When the charged particles, like protons, smash into one another at such high speeds, the energy of the impact becomes matter in the form of new particles or subatomic particles.
  • So, the LHC can essentially “produce” subatomic particles.

 

 

What this detection of neutrinos revealed?

This reported detection of neutrino interactions reveals two major things/

  • First, it verified that the position forward of the ATLAS interaction point at the LHC is the right location for detecting collider neutrinos.
  • Second, the efforts demonstrated the effectiveness of using an emulsion detector to observe these kinds of neutrino interactions.

 

What is an emulsion detector?

  • FASERnu, a neutrino subdetector, is what is known as an emulsion detector.
  • Lead and tungsten plates are alternated with layers of emulsion: During particle experiments at the LHC, neutrinos can collide with nuclei in the lead and tungsten plates, producing particles that leave tracks in the emulsion layers.
