    Naturalness and new principle in field/string theory

    Date: March 23 (Fri) 14:20-15:20
    Place: Room 815
    Speaker: Prof. Hikaru Kawai (Kyoto University)

    The observed Higgs mass indicates that the Standard Model (SM) can be valid up to near the Planck scale, that is, all the couplings remain perturbative and the Higgs potential is stable. From string-theory point of view, this fact indicates the possibility that the SM is directly connected to string theory at the string scale. Furthermore, the Higgs potential can be very small and flat around the Planck scale by tuning the top quark mass with in the experimental error. This fact, the so-called criticality of the SM, suggests that something non-trivial is happening around the Planck scale and that the SM remains valid to the scale without much modification. In this talk, we discuss possible mechanisms or new principles to explain the criticality, and try to make physical predictions to test them.

Journal Club/Seminar Schedule

To Interested Students (給有興趣加入本組的同學):

We are always welcoming enthusiastic advanced undergraduate and beginning graduate students joining our group. While you will formally have a faculty member in our group as an advisor, we share most of activities such as seminars and journal clubs, also resources and office space together.

For the basic backgrounds to start doing research in our group, we expect you to have a solid course on quantum mechanics (roughly at the level of Sakurai), also some rudimentary knowledge of quantum field theory (at least Part I of Peskin & Schroeder). Our group members will also run various advanced courses during the semester, so please stay tuned.

Please feel free contacting any of us about possible undergraduate research and graduate study opportunities!
