As @Stone-Zeng pointed out, `unicode-math` isn't compatible with many traditional packages. In particular (for me), it appears to be incompatible with `hepparticles`. It also seems to have trouble producing bold...

See the MWE in https://github.com/matze/mtheme/issues/306. `unicode-math` is loaded by Metropolis, so it happens after `hepparticles` (which is loaded by `hepnicenames`.

The sans-serif should just be a copy of the normal version (since this is a sans font).

Has there been any progress? I'm trying to use a sans serif math font (Fira Math). A number of characters are missing, which MdSymbol has defined, but trying to use...

MdSymbol has an Opentype version, which is what I'm trying to use. It actually seems to work fairly well, and using the range option I've got it using MdSymbol as...

#45 is a close match, and it was closed and merged here. Maybe you could reopen that?

Wouldn't that change everything?
