Lagrangian Identity and Mass Evolution of Particle-like Objects in Nonminimally Coupled Gravity

S. R. Pinto, P. P. Avelino

The paper derives a general Lagrangian identity for Nambu‑Goto p‑branes and shows that in scalar‑tensor gravity with nonminimal matter couplings, the rest mass of particle‑like obj…
