High energy particle physicists have discovered the possible evidence of quasi particles

According to recent reports, a group of energetic particle physicists say they have collide with protons with the Large Hadron Collider (LHC), and find possible evidence of sub atomic quasiparticles that have been pursued since 70s of last century. They are called “odderon”. They say that the latest research can be a supplement to the standard model of particle physics.

This is the latest research by more than 100 physicists in the LHC full section elastic scattering detector experiment (TOTEM) group. In the experiment, LHC runs at the energy of 13TeV (1TeV=10 billion EV). Under this energy, the proton can get the fastest collision speed, and there are billions of protons colliding every second. By comparing the current results with the measurement results of a low power particle accelerator at lower energy, the TOTEM can carry out the most accurate measurements to date.

The new discovery is related to the hadron (including the family of particles of protons and neutrons), and the hadrons are “glued” to the quarks and gluons. The researchers explained that in all previous proton collider experiments, the scientists found only between different proton even gluon exchange of evidence; and in the new experiment, they use more energy and more accurate observation of potential evidence odd gluon exchange between protons was found.

Christopher Ruvallon, a professor of physics and astronomy at University of Kansas, said, “until now, most models have thought that gluons are always even. Now, for the first time in our new energy level, we find that the new results are incompatible with the traditional models assuming that the number of gluons is even. This is probably the first time we have seen the odd number exchange of gluons.

The researchers say that odderon can be seen as a result of all types of odd number gluon exchange, and the latest discovery provides new details for the particle physical standard model. Moreover, in the TOTEM experiment, the fast timing detector used to measure the proton flight time in LHC can also be used in medical, space physics, such as helping NASA measure cosmic rays and seawater desalination.

“Odderon is very important for us to understand the strong interactions in the standard model,” the expert said. But at present, as an effective degree of freedom of interaction, odderon still has many unsolved mysteries — especially the evolution rule of odderon with energy, which needs more accurate measurements of high-energy physics experiments to further reveal.
