There is some skepticism around this to say the least[1]. The core of it is that this group has found new bosons twice before: The Atomki group has produced three previous papers on their beryllium-8 experiments — conference proceedings in 2008, 2012 and 2015. The first paper claimed evidence of a new boson of mass 12 MeV, and the second described an anomaly corresponding to a 13.45-MeV boson. (The third was a preliminary version of the Physical Review Letters paper.) The first two bumps have disappeared in the latest data, collected with an improved experimental setup. “The new claim now is [a] boson with a mass of 16.7 MeV,” Naviliat-Cuncic said. “But they don’t say anything about what went wrong in their previous claims and why we should not take those claims seriously.” [1] https://www.quantamagazine.org/new-boson-claim-faces-scrutiny-20160607/ https://www.quantamagazine.org/new-boson-claim-faces-scrutin...
