Hello, I am hunting informations about new physics. I am starting a phd in theoretical high energy physics. because of the funding (the part that gives nightmares) the subject HAS TO BE related to neutrino physics (in fact I am in a leading group in this field). So, what do you think (personal opinion) is the best link : neutrinos -> new physics ? Double beta decay ? Leptogenesis ? flavors ? ... Please, tell me what you think. Thanks in advance.
