    Graduate Effective Lagrangian: Breaking Causality or Non-Local?

    As I have read, the effective Lagrangian are non local sometimes, does that mean they break causlaity ? Are they non local because the heavy particles ( propagators) are integrated out?

    Graduate What is the more puzzling our universe with inflation or without it?

    Hi all, I know that inflation solves shortcomings of Standard big bang cosmology, but doesn't intoducing inflation puts us in another puzzle , what is the mechanism which is responsible for inflation? I mean what is the more puzzling our universe with inflation or without it?

    Graduate Are monopoles a problem for all gauge groups in GUT theories?

    Hi All I have some questions about monopoles, I would be grateful if someone help me in answering them. 1-Does all GUTs gauge groups simple and semi simple suffer from the monopoles problem? 2- If semi simple groups suffer from the above problem why standard Model doesn't produce monoples...

    Graduate Existence of virtual particles

    Thanks for all answers, but I still have some questions, I would like someone help me in answering them. 1-How another interpretation of QM explain a virtual particle created from nothing (virtual particle depend highly on energy- time uncertanity)? 2-How the energy -time uncertanity relation...
