So guys, i've been essentially self studying AS physics so far and have amassed a plethora of questions which keep me up at night... well kind of...
1. How can Pi Mesons (neutral) exist if they consist of a quark ant quark pair ( d anti d)(u anti-u): why do they not annihilate one another?
2. What is the difference between interaction and decay, as protons change into neutrons, emitting a positron and neutrino yet are stated as fundamentally stable particles?
3. what does a K+ meson decay to form?
4. Can particles decay to form more massive products via weak interaction, or is it essential for strong interaction to result in more massive products, with kinetic energy converted to mass?
5. Why do leptons decay( ie muons to electrons) if they are fundamental?
6.How can neutrinos have antiparticles if they possess no charge?
7. What is strangeness and are particles only deemed strange due to their abnormally long life spans before decay(ie K+ mesons)
Thank you to anyone who can help because not knowing these questions has hindered my early understanding of physics. Any aid at all would be much appreciated!
I've moved this into the physics forum for you
