We first review a known simple 1+1 model and compute the amount of particle creation. Then we explore a generalization of this model regarding the kind of expansion and the diferences in the particle creation density.5 p.application/pdfengcc-by-nc-nd (c) Plandolit, 2017http://creativecommons.org/licenses/by-nc-nd/3.0/es/Partícules (Física nuclear)Expansió de l'universTreballs de fi de grauParticles (Nuclear physics)Expanding universeBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
