چکیده
A particular kind of quintessence is considered, with equation of motion pQ/ρQ = −1, corresponding to a cosmological term with time-dependence Λ(t) = Λ(t0)(R(t0)/R(t)) P which we examine initially for 0 ≤ P < 3. Energy conservation is imposed, as is consistency with big-bang nucleosynthesis, and the range of allowed P is thereby much restricted to 0 ≤ P < 0.2. The position of the first Doppler peak is computed analytically and the result combined with analysis of high-Z supernovae to find how values of Ωm and ΩΛ depend on P .

The production of Charmonium states η c and hc( P1) at fixed-target experiment of pN collisions at HERA-B is considered. It is found that the HERA-B at DESY is one of the best machines in further confirming and detecting these two kinds of Charmonia in the near future.

Spacetime, understood as a globally hyperbolic manifold, may be characterized by spectral data using a 3+1 splitting into space and time, a description of space by spectral triples and by employing causal relationships, as proposed earlier. Here, it is proposed to use the Hadamard condition of quantum field theory as a smoothness principle.
