It turns out that an electron is almost perfectly round. What does this mean for physics?
Electrons are almost perfectly round. It showed a study published recently in the journal Nature. Why is it important? Because more flattened shape could hint at the presence of invisible subatomic particles. And therefore, this result complicates the search for new physics. Electronic acquires its shape depending on how positive and negative charges are distributed inside the particles. The best theory of the behavior of particles - Standard model - stands on the fact that the electron must have an almost perfect figure.
However, some theories suggest that the electron environment hypothetical subatomic particles can create a slight separation between the positive and negative charges and give electronic form pears. This charge separation is called an electric dipole moment (EDM). Search electron EDM can show whether there is next to no electron a particle does not exist in the Standard Model.
What forms of the electron?
Experiment Advanced Cold Molecule Electron Electric Dipole Moment, or the ACME, conducted at Harvard University, said electron EDM with unprecedented precision - and did not find any signs of flattening. This result could complicate the work of the Large Hadron Collider, located near Geneva, which is looking for new physics beyond the Standard Model. LHC colliding particles like protons together at high speed to create new particles and probe their properties. Physicists want to find signs of the particles, which are not included in the Standard Model, because this theory can not explain some important nuances of the universe - such as why more matter than antimatter. So far, the LHC remained with nothing.
New measurements show that any additional particles that may exist, will be beyond the capabilities of the LHC detection. Perhaps the future will be able to beat the LHC collider.
