A new solution has been proposed for a long-standing problem in particle physics: why is the Higgs boson, a fundamental particle responsible for giving other particles mass, so light? The answer may lie in a phenomenon known as self-organised criticality.
The Higgs mechanism is a crucial part of the Standard Model of particle physics, which describes how fundamental forces and particles interact. However, it relies on an unnatural fine-tuning to explain why the Higgs boson’s mass is so small compared to other particles. This has led physicists to search for alternative explanations.
One possibility is that the universe underwent a period of rapid expansion in the early stages of its formation, known as inflation. During this time, the energy density of the universe would have been incredibly high, causing the Higgs field – a fundamental field that gives mass to particles – to fluctuate wildly. If these fluctuations were strong enough, they could have driven the Higgs boson’s mass down to its current value.
However, this idea runs into problems when trying to reconcile it with observations of the cosmic microwave background radiation, which is thought to be a remnant of the early universe. The data suggests that inflation didn’t occur at such an extreme scale, making it difficult for the Higgs boson’s mass to be driven down in this way.
The new solution proposes that self-organised criticality could be responsible for the Higgs boson’s light mass. This phenomenon occurs when a system, such as a network of interacting particles or fields, reaches a critical point where its properties change dramatically. In the case of the Higgs field, this critical point could have been reached during the early universe’s rapid expansion.
At this critical point, the fluctuations in the Higgs field would have become so strong that they would have driven the boson’s mass down to its current value. This solution has the advantage of being compatible with observations of the cosmic microwave background radiation, making it a more viable explanation for the Higgs boson’s light mass.
The proposal also suggests that the universe may be in a state of self-organised criticality even today, which could have implications for our understanding of the cosmos. If this is the case, it could mean that certain physical phenomena, such as the formation of galaxies or the evolution of life on Earth, are influenced by the same underlying mechanisms.
