Higher-Spin Gravity

October 23, 2019

Electromagnetism, nuclear forces, gravity. Could there be any other types of forces? Analysing generalised Higher-Spin interactions is an interesting approach to understand quantum gravity. Recent results have shown that such higher-spin theories are strongly restricted by gauge symmetry. more
