Rob Klabbers, PhD student at DESY, received a PIER travel grant and went to the "Scattering Amplitudes: from Gauge Theory to Gravity" conference held at the Kavli Institute for Theoretical Physics (KITP) in Santa Barbara. Here is his report.

PIER recently funded my travel to the conference "Scattering Amplitudes: from Gauge Theory to Gravity" held at the Kavli Institute for Theoretical Physics (KITP). This conference was very interesting for me from the perspective of my doctoral thesis, for which I study observables in physical models with a high degree of solvability. Scattering amplitudes are very physical observables and therefore interesting to many physicists. The conference is embedded in a semester-long program inviting experts from all over the world to spend time at the KITP to collaborate on topics in the field, making Santa Barbara the place to be if one wants to learn more about recent advancements in scattering amplitudes. The conference itself was very relaxed and lively due to the informal atmosphere created by the program, since there was ample time to discuss things. Actually, the beautiful scenery surrounding the KITP might also have contributed to the great atmosphere, who doesn't relax while enjoying looking out over the Pacific ocean?

The talks during the week gave me a great overview of the current important questions in scattering amplitudes and I was happy to have the opportunity to ask any questions. The UCSB-campus itself offered also other interesting talks, I managed to attend other talks in high-energy physics and mathematics during my stay and interact with the local graduate students and staff members, which was very valuable. Finally, California has a lot to offer for recreation: in the free time I had there I went on a camping trip to Joshua Tree National Park for hiking and climbing, a great experience.

All in all the conference was very succesful for me: I learnt a lot about scattering amplitudes and met a lot of people in the field. The great weather and surroundings in Santa Barbara made the entire experience even more enjoyable for me. Thanks PIER!
