Reconstructing Supersymmetric Theories at High Energy Scales

G. A. Blair, W. Porod, P. M. Zerwas

Abstract

We have studied the reconstruction of supersymmetric theories at high scales by evolving the fundamental parameters from the electroweak scale upwards. Universal minimal supergravity and gauge mediated supersymmetry breaking have been taken as representative alternatives. Pseudo-fixed point structures require the low-energy boundary values to be measured with high precision.

Reconstructing Supersymmetric Theories at High Energy Scales

Abstract

We have studied the reconstruction of supersymmetric theories at high scales by evolving the fundamental parameters from the electroweak scale upwards. Universal minimal supergravity and gauge mediated supersymmetry breaking have been taken as representative alternatives. Pseudo-fixed point structures require the low-energy boundary values to be measured with high precision.

  • Figure 1: mSUGRA:Evolution of (a) gaugino and (b) sfermion mass parameters in the bottom--up approach. The mSUGRA point probed is characterized by the parameters $M_0 = 200$ GeV, $M_{1/2} = 190$ GeV, $A_0$ = 550 GeV, $\tan \beta = 30$, and $\mathrm{sign}(\mu) = (-)$. [The widths of the bands indicate the 95% CL.]
  • Figure 2: GMSB:Evolution of sfermion mass parameters in the bottom--up approach. The GMSB point has been chosen as $M_m = 2 \cdot 10^5$ TeV, $\Lambda = 28$ TeV, $N_5 = 3$, $\tan \beta = 30$, and $\mathrm{sign}(\mu) = (-)$. [The widths of the bands indicate the 95% CL.]
