The Higgs Boson, Part II - What is Mass?

The video explains how the Higgs field gives particles mass, differentiating it from the Higgs boson. It begins by defining mass and masslessness, noting that massless particles travel at the speed of light. The Higgs field, with its non-zero value everywhere, allows particles to interact with it, appearing to have mass. This interaction is crucial for particles to not always travel at light speed. The Higgs field also interacts with its own excitations, giving mass to the Higgs boson. Despite the challenges, the Higgs field is essential for the existence of mass, allowing particles to move at various speeds.

What is the defining characteristic of a massless particle?

• It can travel at any speed.

• It has a high mass.

• It cannot move.

• It travels at the speed of light.

How does the Higgs field affect massless particles?

• It slows them down by interacting with them.

• It speeds them up to the speed of light.

• It makes them disappear.

• It changes their charge.

What is unique about the Higgs field compared to other fields?

• It does not interact with any particles.

• It only interacts with electrons.

• It has a high value everywhere.

• It has a zero value everywhere.

What does the Higgs field do to the Higgs boson?

• It gives it mass.

• It makes it invisible.

• It gives it a negative charge.

• It makes it massless.

Why does the Higgs boson have more mass than electrons and protons?

• Because it travels faster than light.

• Because it is made of different particles.

• Because it is larger in size.

• Because it interacts more with the Higgs field.
