● We have discussed how gauge bosons obtain mass by a gauge that absorbs the Goldstone bosons in the theory. ● As a complex doublet has four degrees

cannot use QCD Lagrangian for perturbation theory anymore quarks and gluons form a plethora of hadrons?. protons and neutrons

Besides a proof of Conjecture 1.4 one might consider special subclasses of general graphs to obtain stronger bounds on the minimum oriented diameter.. Thomassen, Distances

Here, we develop a simple, bottom-up model to estimate a practical minimal threshold for the final energy consumption required to provide decent material livings to the entire

We present exact mixed integer programming approaches including branch-and-cut and branch- and-cut-and-price for the minimum label spanning tree problem as well as a variant of

The priors and posteriors for the gauge sector parameters, in figure 6, look much the same as in the M4DCHM 5−5−5 , with the NGB decay constant posteriors concentrated well above

Since the covariance matrix can be estimated much more precisely than the expected returns (see Section 1), the estimation risk of the investor is expected to be reduced by focusing
