The S-matrix bootstrap is a numerical method that can be used to determine or constrain the scattering amplitudes of particles in quantum field theory using simple principles. Over the past few ...

If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up.

With just a handful of assumptions, string theory stands alone. Based on the idea that all subatomic particles are made up of vibrating strings of energy, string theory is a candidate for a “theory of ...

Visualization of the allowed values of "dial settings" in the scattering amplitudes that describe the probability for particles to interact in the models introduced in this new work. The regions in ...

Here’s what you’ll learn when you read this story: String theory attempts to unify general relativity and quantum theory. Popular in the 1990s, string theory fell out of favor as it failed to provide ...
