Sharing source code for a HEP experiment is not that easy or possible at sometimes. A lot of stuff is done by different group and whole framework used and overall a lot of raw data collected and reconstructed involved. To analyze those even if available you willl need a lot of people with a lot of resources. So even it made available (which would be a lot of efforts itself) it wouldn't make much sense for replication purpose.

How is it possible to peer review a paper when the only people qualified to do so are the one's involved in the research. Seems like a massive issue. Don't want to cast to much shade here, but there's a fair number of people that called out high energy physics for having problematic methodology. See Constructing quarks by Andrew Pickering. Ultimately, it should be CERNS job to release the data, yes even if it is terabytes in size, because that's the whole point of science.

The fine structure constant is a bigger mystery in my opinion, though physics has alot of unexplained constants right now.

One thing I've always wondered about when it comes to new process design at smaller scale: how much actual quantum mechanics is actually needed to get the job done?

And ... if the answer is, as I suspect, a lot, what kind of numerical methods and processes are used to design and simulate these tiny quantum mechanical machines?

[EDIT] I mean, when taking a basic QM course, there is a lot of contorsions to try and find analytical solutions to the Schrödinger equation, but as soon as you have three particle interacting with each other, analytical methods run into a wall.

Am I right to think that sub-10nm process design is all done numerically?

Anyone who happens to work on this type of problems care to give pointers?

Solid State Physics has a bunch of different types of models to try to explain the behavior of electrons in semiconductors and conductors. Most of them are only valid under specific situations and they sometimes give erroneous results unless you apply them carefully. That being said, your absolutely right that the industry uses approximations. They usually use some kind of simulation physics package similar to the ones used by EE engineers when designing circuits.
