For the conservation to find particle X I put photon, it doesn't have a charge, lepton number = 0, baryon number = 0, doesn't violate anything so would I by any chance get the mark?

I don't think so, energy and momentum won't be conserved
^^ ignore that - read this. The explanation looks kinda long
So you suggesting we need to know about Charge Conjugation Symmetry at AS Level?
No. This exact question came up before in a paper (June 14) and the reasoning behind the neutral pion was to conserve charge, except they gave you a list of particles to chose from. I'll be honest here, aside from the obvious charge conservation the only reason I knew it was the neutral pion was because I'd seen the question before
That's A levels for you haha. You might get the mark, who knows

Ah lucky you, I should have done June 14 before the exam :/ I made the mistake of doing all the old papers because I'd never seen them before but had no idea it was basically the same question, ik I'll get some method marks for the conservation laws behind it but not sure about the photon since it doesn't violate any AS conservation laws haha
