Entanglement entropy, Monte Carlo event generators, and soft gluons DIScovery Open
We study entropy production in Deep Inelastic Scattering using Monte Carlo simulations. We show that the dominant contribution to entropy is due to soft gluons. This contribution is usually neglected in standard Monte Carlo approaches, sin…
