Sean Carroll's Mindscape: Science, Society, Philosophy, Culture, Arts, and Ideas
289 | Cari Cesarotti on the Next Generation of Particle Experiments

You can do things that are just completely new particles or dark matter related or things like that. And a lot of the times you just need higher energies to really see the effects of these particles show up. So the energy frontier, I think, is really the most compelling reason to say that a muon collider is something that we shouldn't invest in.

In terms of other physics programs, as we said in the beginning, the Higgs boson is definitely the most mysterious particle. And depending on exactly your ideology, you may or may not say that a Higgs boson is new physics. But I'm not NEMA, so I'm not going to say that.

But you can study a lot of Higgs bosons in a way that you can't do at the LHC, and you can do it in a much cleaner environment in some ways, too. So attend to EV muon clutter. Given the physics program that we hope to run, you can produce 10 million Higgs bosons. And with 10 million Higgs bosons, you can study a lot.

So if you really want to flush out the story about how the Higgs couples to itself, how it couples to other particles, how the symmetry is restored in the electroweak sector at higher energies, a muon collider is also a very good tool for that.

So while the E plus E minus machine is usually what's billed as the Higgs factory, a muon collider could also have a lot of the complementary and overlapping physics program of that kind of machine too. So studying the Higgs and going to higher energies to give you the sound bite are really what we want to do with a muon collider.

But those are basically the only two things that I even know what to suggest in terms of trying to resolve things like the hierarchy problem or dark matter or stuff like that.

Okay. Well, step one, um, have three cups of coffee and two existential crises a day. Um, but okay. So my favorite model. I'll give you two answers to this. There's one model that I just hope is right and I just hope is out there just because it'd be nice. So I really hope that there's a new Z prime or vector boson out there. So I want some new spin one particle that looks like a massive photon.

We often will call that the dark photon or a Z prime. I just want that thing to be out there.

I think having the existence of that particle would just open so many interesting questions and it could be the portal to dark matter, it could be the portal to something else interesting, it could be something that mixes with the electroweak sector and there's all sorts of new complicated stuff when we have to reinterpret everything. So I really hope it's out there.

Yeah, basically a heavy photon is what we're looking for. And the reason that that's exciting is because whenever you have a spin one vector particle, it couples to something else. It's charged under something else. So it could be a portal into some whole new world of physics.
