Okay, opening the decorider there is a cup standing next to it with some writing on it. I can't figure out all of it, can anyone help?

Now, what i have so far:

- first line is typical tensor stuff with the typical index battles - so looks General Relativity. Some part of an equation related to the energy stress tensor? Though that is also used in QFT (quantum field theory), with a F with two indices often denoting the EM-field strength (more or less the same thing as in GR).
- A Crossed D and a Psi? Must be quantum mechanics with Feynmans slash notation. The term itself doesn't tell me much though.
- the next line has a "h.c." in it - must be Hermitian conjugate. So also quantum mechanics stuff. the term before that has bad handwriting and i cannot figure each letter. but looks like an interaction term between a Dirac field and a scalar one from QFT. Yukawa?
- last line is also definitvely from QFT with V(Phi) being a self-interaction of the scalar field. can't make sense of the term before that though, as it looks like another self-interaction term but it's incomplete and hard to read due to the space curvature of the cup...

So that's what i can figure on short notice but i haven't worked with that stuff for quite a long while now. Not much use for it in the private sector
