2/2015 Michael (Misha) Smolkin accepted our offer for a faculty position, joining the high energy group in summer 2016. Best wishes for success to Misha and the whole group!

8/2014 "Leading anomalies, the drift Hamiltonian,  and the relativistic two body problem" by Barak Kol and Bernard Nabet appears. This work proposes to solve the equations of motion by concentrating on relativistic anomalies and utilizing the Hamiltonian averaging method for a rather elegant and intuitive formulation.
    Presented "The effective field theory approach to the two body problem in Einstein's gravity" at the Vienna university of technology and at the Wigner research center (Budapest).

6/2014 "1-loop color structures and sunny diagrams" by Barak Kol and Ruth Shir appears

4/2014 "Color structures and permutations" and "Perturbative gauge theory and 2+2=4" by Ruth Shir and Barak Kol appear. These are our first papers on scattering amplitudes. They were presented at the Oxford Mathematical Physics group.

1/2014 Congratulations to Ruth for winning the Meidan fellowship (20k$/year for 3 years)
          Presented "Self force and equivalent periodic sources" (see 7/2013 below) at  "Black holes and quantum information" 12-17.1.2014, Weizmann.

9/2013 Presented the talk "How perturbative field theory could have been discovered in Einstein's gravity" at the Institute for Advanced Study, Princeton.

7/2013 Teaching evaluation for the recently given course "physics of musical instruments" (a student's seminar) ranks the course 1st among the department's 54 courses.

7/2013 "Self force and equivalent periodic sources" appears and is presented in Capra 16 together with an invited review talk. This work suggests to change the way researchers have been thinking about the self force and have been computing it over the last two decades. Here is an informal introduction.
