Qcd Corrections To Properties Of Technipions In Technicolor Theories , David H. Slaven

#### Qcd Corrections To Properties Of Technipions In Technicolor Theories , David H. Slaven

*Retrospective Theses and Dissertations*

In this work we calculate QCD corrections to technipion processes in a one family technicolor model. Our approach is to use an effective technipion Lagrangian analogous to the effective Lagrangian of QCD. The effective Lagrangian includes the Wess-Zumino-Witten Lagrangian (adapted to technicolor), and we gauge the QCD subgroup of the chiral symmetry to obtain couplings between the technipions and gluons. Here we examine processes involving the P[superscript]0[superscript]', a colorless, neutral, electroweak singlet, and the lightest technipion in a one family technicolor model. In addition to the Wess-Zumino-Witten Lagrangian, we assume couplings between technipions and ordinary fermions, due ...

Neutral Technicolor Pseudo Goldstone Bosons Production And Qcd Background At The Ssc , Wang-Chuang Kuo

#### Neutral Technicolor Pseudo Goldstone Bosons Production And Qcd Background At The Ssc , Wang-Chuang Kuo

*Retrospective Theses and Dissertations*

The production of the neutral technicolor pseudo Goldstone bosons, P[superscript]0[superscript]' and Psp80[superscript]', at large transverse momentum in pp collisions, pp → g(q)P[superscript]0[superscript]' (Psp80[superscript]')X has been investigated in reactions at a high energy collider such as the SSC. The major two-body and three-body decay modes in tree diagrams are investigated in detail. The t[macron] t decay channel would dominate both the decays of P[superscript]0[superscript]' and Psp80[superscript]' if it is allowed. Otherwise, gg and 3g will be the dominant decay modes unless the mass of the P ...

Measurement Of [Alpha Subscript S]From Energy-Energy Correlations In E+E- Annihilation At 29 Gev , Hsiao-Ying Chao

#### Measurement Of [Alpha Subscript S]From Energy-Energy Correlations In E+E- Annihilation At 29 Gev , Hsiao-Ying Chao

*Retrospective Theses and Dissertations*

We have studied the energy-energy correlation in e[superscript]+e[superscript]- annihilation into hadrons at √s = 29 GeV using the TPC/2[gamma] Detector Facility at PEP. We found that [alpha][subscript]s = 0.161 ±.004 ±.011 for the average hadronic event sample using GKS matrix elements and LUND symmetric string fragmentation.
