Definitions

- noun A spectral line having more than one component, representing slight variations in the energy states characteristic of an atom.
- noun Any group of subatomic particles that are similar in most properties, but have different electric charges, such as the nucleons, which form a doublet, or the pions, which form a triplet.

November 25th, 2009 at 2:56 pm a higher family structure, say a fourth quark multiplet?
-
In particular does quantum chromodynamics QCD have a higher family structure, say a fourth quark multiplet?
-
This might also mean there is a higher mass multiplet of leptons as well, though those should have been detected if they exist.
-
This gets of course into string theory, and the closed string which carry the supergravity multiplet couples to the D-brane of the universe more strongly by coupling to or transforming to an open IIB string.

-
In multicomponent DM scenarios, a dark force would preclude large shifts in the rate for Higgs decay to two photons associated with DM-multiplet loops that might otherwise lead to measurable deviations at the LHC or a future linear collider.

-
He introduced a new fundamental characteristic of a multiplet called its hypercharge.
-
This is defined as twice the mean value of the charges in the multiplet.
-
For example, all closed string modes may be thought of as components of a gigantic stringy "gravitational multiplet" and all other branes are generalizations of a string (and they can be dual to strings in various dual descriptions).

With over a decade of continuous improvement, a host of incredibly useful features to help students, chemists, and spectroscopists have been introduced to help them get the most out of their data NMR data; automatic extraction of multiplet patterns and coupling constants, assignment of multiplets to atoms in a chemical structure, robust and sophisticated macro capabilities, and powerful reporting tools to name a few.
-
If this is not the case, then the multiplet structure can still be predicted by considering first the coupling to one set of equivalent J-coupled nuclei and predicting that the effect of the remaining nuclei will cause additional splitting of the multiplet generated by interaction with the first set.
