What are these?
We experience tc, tg and tT as a whole, just as in any direction space is just x; then tc, tg and tT are undifferentiated and so are these particles. However, if our sight is a charge phenomenon (along tc only) then otT(x,tc,tg) and otg(x,tc,tT) can impart energy along tc and maybe slow/speedup ptc and induce invisibility. The notation otx is used here.
These O particles can still affect the space dimensions via the space-time energy oscillations in photons. And can couple energy directly onto the time dimension. Indirectly, they require a photon or a basic particle to be detected in space. In the case of the left most O particle in the diagram, ptT(x1,x2,tg), ptT(x1,x2,tc), ptc(x1,x2,tg) or ptg(x1,x2,tc); photons with energy oscillating in either tg or tc time dimension and a space dimension, or a stationary basic particle where the first entry inside the parenthesis is replaced with a time dimension and has energy oscillation between tc or tg and a space dimension. That is, q(tT,x,tg), T(tc,x,tg), T(tg,x,tc) and g(tT,x,tc).
OK?!
