  • Strong interaction is really designed as a baryonic thing, leptons have no color charge (which is another way to say that they transform as SU(3) singlets). Leptons do not interact with gluons.
    Not at tree-level anyway. See for example this list of vertices.

    At loop levels, it’s possible to imagine an electron decaying into neutrino+W, then W into two quarks who can then interact with gluons, but as it’s down a couple of orders in perturbation theory so probably much too weak to hold a nucleus together. Not an expert in particle physics so I do not know with certainty whether a couple-of-loops interaction can have a measurable effect.






  • The scifi “dimension” is as meaningless as “plane of existence”

    Does not sound too meaningless to me, but I’m used to calling that a universe 😁

    think about the sentence “the universe is a part of our dimension”

    I’m trying ahah. But if you call the universe a dimension, which subpart of it do you call a universe? The observable universe maybe? I mean it makes sense to say that the observable universe is part of our universe. Still sounds strange the way it is presented by OP.











  • US officials, unhappy with the scuttled EU deal, saw a similar chance in the Maidan protests.

    ,

    It’s an overstatement to say, as some critics have charged, that Washington orchestrated the Maidan uprising. But there’s no doubt US officials backed and exploited it for their own ends.

    Your source states very clearly that the US did not orchestrate the Maidan protests, and that its involvement was due to the aborted EU-deal.

    Nothing in there about the Maidan government wanting to join NATO, aside from one reference to Putin’s paranoia about it :

    After Putin moved to secure the Crimean naval base from NATO control

    Indeed, the article referenced in this sentence says:

    “Our decision on Crimea was partly due to … considerations that if we do nothing, then at some point, guided by the same principles, NATO will drag Ukraine in and they will say: ‘It doesn’t have anything to do with you.’”

    So, according to your source, Crimea was not annexed in reaction to Ukraine giving up its neutrality, but in prevision of it.
