Negative T from a dynamical left-handed neutrino mass
B. Holdom
We show how a dynamical Majorana mass for a fourth family left-handed neutrino can make a significant negative contribution to the electroweak correction parameter T without making…
Are Four-Fermion Operators Relevant for the Fermion Mass Problem?
B. Holdom
Four-fermion operators may have large anomalous scaling and become relevant operators in some strongly interacting gauge theories. We present a detailed model which illustrates som…
Chiral Symmetry Breaking via Multi-fermion Green Functions
B. Holdom, G. Triantaphyllou
Previous results on fermion chirality-flipping four-point functions are extended to gauge theories. The problem is purely non-perturbative, and it is approached by truncati…
Critical Behavior of a Four-Fermion Schwinger-Dyson Equation
B. Holdom, G. Triantaphyllou
We study the Schwinger-Dyson equation associated with a chirality- changing fermion 4-point function in a strongly-coupled gauge theory. After making appropriate simplificat…
Momentum dependent quark mass in two-point correlators
B. Holdom, Randy Lewis
A momentum dependent quark mass may be incorporated into a quark model in a manner consistent with dynamically broken chiral symmetry. We use this to study the high behavior…
What can a relativistic quark model tell us about charmed mesons?
M. Sutherland, B. Holdom, S. Jaimungal +1
A relativistic quark model is extended to incorporate chiral and gauge symmetries. We obtain the DD*pi and DD*gamma couplings and find that the ratio Gamma(D*0->D0pi0)/Gamma(D*0->D…
