Fermion selfenergies and pole masses at twoloop order in a general renormalizable theory with massless gauge bosons
Abstract
I present the twoloop selfenergy functions and pole masses for fermions in an arbitrary renormalizable field theory in the approximation that vector bosons are treated as massless. The calculations are done simultaneously in the massindependent MS, DR, and DR{sup '} renormalization schemes, with a general covariant gauge fixing, and treating Majorana and Dirac fermions in a unified way. As examples, I discuss the twoloop strong interaction corrections to the gluino, neutralino, chargino, and quark pole masses in minimal supersymmetry. All other twoloop contributions to the fermion pole masses in softly broken supersymmetry also can be obtained as special cases of the results given here, neglecting only the electroweak symmetry breaking scale compared to larger mass scales in twoloop diagrams that involve W or Z bosons.

Strong and Yukawa twoloop contributions to Higgs scalar boson selfenergies and pole masses in supersymmetry
I present results for the twoloop selfenergy functions for neutral and charged Higgs scalar bosons in minimal supersymmetry. The contributions given here include all terms involving the QCD coupling, and those following from Feynman diagrams involving Yukawa couplings and scalar interactions that do not vanish as the electroweak gauge couplings are turned off. The impact of these contributions on the computation of pole masses of the neutral and charged Higgs scalar bosons is studied in a few examples. 
Supersymmetry at ordinary energies. II. R invariance, Goldstone bosons, and gaugefermion masses
We explore the observable consequences of supersymmetry, under the assumption that it is broken spontaneously at energies of order 300 GeV. Theories of this sort tend automatically to obey a global R symmetry, which presents us with a choice among phenomenologically unacceptable alternatives. If the R symmetry is broken by scalar vacuum expectation values of order 300 GeV, there will be a semiweakly coupled light Goldstone boson, similar to an axion. If it is not broken by such vacuum expectation values but is broken by quantumchromodynamic (QCD) anomalies, then there will be a light ninth pseudoscalar meson. If it ismore » 
Twoloop renormalization of gaugino masses in general supersymmetric gauge models
We calculate the twoloop renormalization group equations for the running gaugino masses in general supersymmetry (SUSY) gauge models, improving our previous result. We also study its consequences on the unification of the gaugino masses in the SUSY SU(5) model. The twoloop correction to the oneloop relation [ital m][sub [ital i]]([mu])[proportional to][alpha][sub [ital i]]([mu]) is found to be of the order of a few percent. 
Infrared singularities and suppression of bosons in massless Abelian gauge theory
Infrared singularities in massless Abelian gauge theory are studied taking into account degeneracy of states. The vacuum polarization causes the physical charge to vanish and suppresses real excitations of the boson field. Nevertheless, in this theory there is a neutral current interaction between fermions. It is concluded that charged massless fermions cannot exist.
