You did it! You discovered the Higgs-boson!

The Higgs field

+

+ The Higgs-Englert field has a central role in our current understanding of the universe. + Through a process called Spontaneous Symmetry Breaking, it is responsible for the masses of all massive fundamental particles that we know of. +

+
+ +
+

What is Spontaneous Symmetry Breaking?

+

+ At every point in space, the Higgs field has a certain strength, a number that tells you how active the field is. + This is quite similar to temperature: You can assign a temperature to every point in a room, and the temperatures might be different for different points in the room and even change with time. +

+

+ The Higgs-Englert field is the most special fundamental field that we know of: It interacts with nearly all of the other fields (like the electron field or the quark fields). + This means that the Higgs field can greatly influence the other fields: If it is active somewhere, then electrons, quarks and other particles in that region will be slowed down by it. + This is equivalent to them gaining mass! +

+

+ But if the Higgs field would have an average strength of zero (as is usual for a field), then we would not be able to observe this slowdown (meaning no mass for other particles). +

+

+ So how come this is not the case? + It turns out that the Higgs field's potential, which governs how much energy is needed to increase its strength, has a very special form (see below). + If the energy density in the universe is low enough, the field will drop down into the valley in the potential. + This means it will be locked to a non-zero strength, and other particles gain mass everywhere in the universe! +

Higgs' contribution

+

+ The mechanism of spontaneous symmetry breaking was discovered and explored by various different researchers. + But it was Peter Higgs who first proposed, in 1964, that we could find evidence of it by searching for a new fundamental particle, now called the Higgs boson. +

+
+ +
+

Discovery at the LHC

+

+ After decades of work, the discovery of the Higgs boson was announced in 2012 by the ATLAS and CMS collaborations at CERN. + In 2013, Englert and Higgs received a Nobel Price for their contributions to the Higgs mechanism and the prediction of the Higgs particle. +

+

+

The future of Higgs physics

+

+ You might think that we now know everything there is to know about the Higgs field, but it turns out that we actually know very little! + Questions like +

+ are sure to have physicists on the edge of their seats for many years to come! +
