These guys in Budapest have used Standard Model type math to find another "hope" for LENR..
and have considered the Coulomb so-called barrier
The assertion by Jarek of p-e-p being the only "hope" is a severe case hypothesis myopia..
There are several hopeful explanations extant..
and in fact a considerable amount of experimental support

Based on our recent theoretical findings (Phys. Rev. C 99, 054620 (2019)) it is shown that proton
and deuteron capture reactions of extremely low energy may have accountable rate in the case of all
elements of the periodic table. Certain numerical results of rates of nuclear reactions of two final fragments of extremely low energy are also given.
New way of thinking about low-energy nuclear reactions (LENR) phenomena is suggested. Possible explanations for the contradictory observations
announced between 1905-1927 and possible reasons for negative results of ’cold fusion’ experiments published recently by the Google-organized scientific group (https://www.nature.com/articles/s41586-
019-1256-6) are given
