Low energy theorems for electromagnetic and gravitational radiation

N.D. Hari Dass
TIFR-TCIS Hyderabad

After explaining the spirit behind the so called low energy theorems, LETs (more accurately, low momentum transfer theorems), I will first demonstrate their great powers in delivering many important results in particle physics. I will then show how Francis Low applied this to electromagnetic radiation. After describing some of Weinberg’s pioneering works in applications to gravitation, I will describe my own work on gravitational radiation using LET’s, reproducing Einstein’s quadrupole formula. I shall bring out various nuances and discuss future prospects.
