A new imaginary particle can solve two main questions of particle physics

Despite the power of the large hadron collider of 13 TeV – this energy is more than enough to reveal many of the elementary particles predicted by theorists – no new particles have been discovered since the Higgs boson in 2012. In the absence of such, many physicists are still hinting at the truth of some “new physics”, beyond the standard model.

In their new work, physicists Yu-Sheng Liu, David McKean, and Gerald A. Miller of the University of Washington in Seattle hypothesized the existence of a new particle. The theory looks very tempting, because it can simultaneously solve two global problems at once: the uncertainty of the proton radius and the anomalous magnetic moment of the muon, which, when measured, differs significantly from the standard model.

“The new particle can solve two seemingly unrelated problems,” Miller said. “We’ll also be doing some experiments that will test our hypothesis once again.”

Physicists describe the hypothetical particle as an “electrophobic scalar boson”. There are currently five bosons in the Standard Model, only one of which is a scalar (Higgs boson), meaning it has zero spin. All five bosons have been experimentally confirmed. One of the distinguishing features of the new hypothetical particles is that, although they are predicted to bind protons and neutrons, this bond is very weak or completely electronless, which makes this imaginary particle “electrophobic”. Scientists have shown how this property of electrophobicity will solve the problem of the proton and muon.
