متن کاملTightly Bound Composite Higgs∗†
We explain general features of the tightly bound composite Higgs models proposed in recent years; walking technicolor, strong ETC technicolor, and a top quark condensate, etc.. These models are all characterized by the large anomalous dimension due to nontrivial short distance dynamics in the gauged Nambu-Jona-Lasinio models (gauge theories plus four-fermion interactions). Work supported in par...
متن کاملA variational study of bound states in the Higgs model
The possible existence of Higgs-Higgs bound states in the Higgs sector of the Standard Model is explored using the |hh〉 + |hhh〉 variational ansatz of Di Leo and Darewych. The resulting integral equations can be decoupled exactly, yielding a one-dimensional integral equation, solved numerically. We thereby avoid the extra approximations employed by Di Leo and Darewych, and we find a qualitativel...
متن کاملTriviality and the Higgs mass lower bound
In the minimal Standard Model, it is commonly believed that the Higgs mass cannot be too small, otherwise Top quark dynamics makes the Higgs potential unstable. Although this Higgs mass lower bound is relevant for current phenomenology, we show that the Higgs vacuum instability in fact does not exist and only appears when treating incorrectly the cut-off in the renormalization of a trivial theo...
متن کاملHiggs and Heavy Quarks Diffractive Production
2.1. Inclusive Higgs production Inclusive Higgs production has been studied in many details [ 2, 3, 4] for the Tevatron energies. The main source for Higgs is gluon-gluon fusion which gives σ(GG → H) = 1pb for Higgs with mass MH = 10GeV [ 4]. The reference point for our estimates is the cross section of Higgs production due to W and Z fusion which is equal to σ(WW (ZZ) → H) = 0.1pb [ 4]. In thi...
