Such a novel collider could mensurate to a greater extent than exactly the properties of the Higgs-boson. But that’s non all, at to the lowest degree according to Lockyer. He claims he knows in that location is something novel to regain too:
“Everybody believes there’s something there, but what we’re right away starting to inquiry is the scale of the novel physics. At what publish energy does this novel physics present up,” said Dr Lockyer. “From a simple calculation of the Higgs’ mass, in that location has to endure novel science. We simply can’t surrender on everything nosotros know equally an excuse for where nosotros are now.”First, allow me notation that “everybody believes” is an declaration advertizement populum. It isn’t solely non-scientific, it is also wrong because I don’t believe it, qed. But to a greater extent than importantly, the declaration for why in that location has to endure novel scientific discipline is wrong.
To laid out with, nosotros can’t calculate the Higgs mass; it’s a complimentary parameter that is determined yesteryear measurement. Same with the Higgs volume equally with the masses of all other uncomplicated particles. But that’s a affair of imprecise phrasing, too I solely choose it upwards because I’m an ass.
The declaration Lockyer is referring to are calculations of quantum corrections to the Higgs-mass. Ie, he is making the good, old, declaration from naturalness.
If that declaration were right, nosotros should accept seen supersymmetric particles already. We didn’t. That’s why Giudice, caput of the CERN theory division, has late rung inwards the post-naturalness era. Even New Scientist took notation of that. But mayhap the word hasn’t yet arrived inwards the USA.
Naturalness arguments never had a enterprise mathematical basis. But then far y'all could accept gotten away maxim they are handy guides for theory development. Now, however, seeing that these guides were bad guides inwards that their predictions turned out incorrect, using arguments from naturalness is no longer scientifically justified. If it always was. This way nosotros accept no ground to hold off novel science, non inwards the not-yet analyzed LHC information too non at a adjacent larger collider.
Of course of written report in that location could endure something new. I am all inwards favor of edifice a larger collider too simply encounter what happens. But delight let’s stick to the facts: There is no ground to squall back a novel regain is roughly the corner.
I don’t squall back Lockyer deliberately lied to BBC. He’s an experimentalist too in all probability truly believes what the theorists tell him. He has all reasons for wanting to believe it. But truly he should know better.
Much to a greater extent than worrisome than Lockyer’s imitation claim is that literally no i from the community tried to right it. Heck, it’s similar the caput of NASA simply told BBC nosotros know there’s life on Mars! If that happened, astrophysicists would collectively vomit on social media. But particle physicists? They all maintain their oral cavity close if i of theirs spreads falsehoods. And y'all wonder why I say y'all can’t trust them?
Meanwhile Gordon Kane, a US-Particle physicist known for his unswerving back upwards of supersymmetry, has made an interesting move: he discarded of naturalness arguments altogether.
You regain this in a newspaper which appeared on the arXiv today. It seems to endure a promotional slice that Kane wrote together with Stephen Hawking some months agone to advocate the Chinese Super Proton Proton Collider (SPPC).
Kane has claimed for fifteen years or then that the LHC would accept to encounter supersymmetric particles because of naturalness. Now that this didn’t operate out, he has come upwards up with a novel ground for why a adjacent larger collider should encounter something:
“Some people accept said that the absence of superpartners or other phenomena at LHC then far makes regain of superpartners unlikely. But history suggests otherwise. Once the [bottom] quark was found, inwards 1979, people argued that “naturally” the transcend quark would solely endure a few times heavier. In fact the transcend quark did exist, but was forty-one times heavier than the [bottom] quark, too was solely found nearly xx years later. If superpartners were forty-one times heavier than Z-bosons they would endure also heavy to abide by at LHC too its upgrades, but could endure detected at SPPC.”Indeed, cypher forbids superpartners to endure forty-one times heavier than Z-bosons. Neither is in that location anything that forbids them to endure four-thousand times heavier, or 4 billion times heavier. Indeed, they don’t fifty-fifty accept to endure in that location at all. Isn’t it beautiful?
Leaving aside that simply because nosotros can’t calculate the masses doesn’t hateful they accept to endure close the discovery-threshold, the historical analogy doesn’t operate for several reasons.
Most importantly, quarks come upwards inwards pairs that are SU(2) doublets. This way in i trial y'all accept the bottom quark, y'all know it needs to accept a partner. If in that location wouldn’t endure one, you’d accept to discontinue the symmetry of the criterion model which was established with the lighter quarks. Supersymmetry, on contrast, has no bear witness with the already known particles speaking inwards its favor.
Physicists also knew since the early on 1970s that the weak nuclear forcefulness violates CP-invariance, which requires (at least) 3 generations of quarks. Because of this, the being of I solely simply wrote 2 weeks agone that the lobbying motion is probable to starting fourth dimension soon. And, lo too behold, hither nosotros go.
In my volume “Lost inwards Math” I analyze how particle physicists got into this mess too also offering some suggestions for how to displace on.
