The Higgs boson

Every boson on the chart so far earns its place the same way: it carries a force. The chart holds one more boson, and it carries no force at all. So what is it for?

Look at the boson column: the photon, the gluon, the W boson, the Z boson. Each one carries a force.

The bosons met so far: the photon, the gluon, and the W and Z bosons — each one carries a force.

The standard model holds a fifth boson. It carries no force. This fifth boson answers a different question: why do fundamental particles have mass in the first place?

This fifth boson is called the Higgs boson. The Higgs carries no force. Instead, it gives fundamental particles their mass.

Every boson but one carries a force. The Higgs gives fundamental particles their mass.

So the sorting line inside the boson family reads: a force-carrier boson passes a force between particles; the Higgs passes no force — it gives fundamental particles their mass. The Higgs is still a boson. It is just not a force carrier.

A chart lists five bosons: the photon, the gluon, the W boson, the Z boson, and the Higgs boson. Which one carries no force?

The photon, the gluon, the W boson, and the Z boson each carry a force.

The Higgs carries no force. It gives fundamental particles their mass.

The Higgs boson carries no force.

Is the Higgs boson a force-carrier boson?

A force-carrier boson passes a force between particles.

The Higgs passes no force.

No. The Higgs is a boson, but not a force carrier.

What does the Higgs boson give to fundamental particles?

Which statement about the Higgs boson is correct?

A student says every boson in the standard model carries a force. Is the student correct?
