* The value of the magnetic moment of the muon (g) is too high. IIRC this result has only a 2.5 or 3 sigma, so it's far from confirmed.
* There are some experiment to prove that the neutrino is a majorana particle and that the neutrino and the anti-neutrino is the same particle. I don't remember any good announcement, so I think that the experiments have still too early results or the results are not interesting. [I don't like this theory, but many people that knows more than me like it.]
That kind of emphasizes the point rather than disproves it, though. Nearly 40 years of physics to pull your examples from, and you pull something from last month, something not confirmed (there's been tons of 2.5-3 sigma results over the past 40 years, but there's a reason physicists have learned to wait for more sigma), and something that is unannounced and may be uninteresting.
I believe there are some other things in that time frame. I believe the discovery that the universe is accelerating in its rate of separation fits in that time frame, and that's pretty big. We don't know how to fit it in with anything, but it's big. And I'd still say confirming Higgs is big.
But... yeah... it is a pretty short list compared to preceding decades.
When I spoke to an exo collaborator he told me that exo put a really tight limit on the rate of neutrino-less double beta decay. If I was a betting man I would put it in the same category as proton decay, another theoretical physics favorite.
* There is a recent 4.5+4.8 sigma excess in neutrinos oscillation that hints a new neutrino https://arstechnica.com/science/2018/06/weird-neutrino-exces... [technical note, you can't add sigmas naively, 4.5+4.8=6.1]
