Abstract
We extend the results of [CGLS22] to higher weight modular forms and prove a rank Tamagawa number formula (also known as the Bloch-Kato conjecture) for modular forms at good Eisenstein primes, under some technical assumption on periods. Under standard hypotheses (i.e. the injectivity of the -adic Abel-Jabobi map and the non-degeneracy of the Gillet-Soul\'e height pairing), we also discuss some partial results towards a rank result. A conditional higher weight -converse theorem to Gross-Zagier-Zhang-Kolyvagin-Nekov\'a\v{r} is also obtained as a consequence of the anticyclotomic Iwasawa Main Conjectures.
