“…In the RPV SUSY scenario we solve the RG equations consistently at 1-loop using the results from[80]. At higher loop level, the decoupled first and second generation squarks would require a refined analysis[81], which is beyond the scope of our work, but our qualitative conclusions concerning gauge coupling unification are unaffected. The impact of the RPV interactions on the running gauge couplings is small as long as the RPV couplings do not develop a Landau pole.…”

Capability of LHC to discover supersymmetry with $ \sqrt {s} = 7\;{\text{TeV}} $ and 1 fb−1

“…The version 7.79 SUSY spectrum calculation includes threshold corrections at each distinct decoupling squark and slepton mass value, whereas previous Isajet versions implemented all squark threshold corrections at a common scale mũ L and all sleptons at a common scale mẽ L [15]. Furthermore, previous Isajet versions included two-loop RGE running for the Cross number of SM process Generator section events QCD: 2, 3 and 4 jets (40 GeV< E T (j1) < 100 GeV) AlpGen 2.6 × 10 9 fb 26M QCD: 2, 3 and 4 jets (100 GeV< E T (j1) < 200 GeV) AlpGen 3.9 × 10 8 fb 44M QCD: 2, 3 and 4 jets (200 GeV< E T (j1) < 500 GeV) AlpGen 1.6 × 10 7 fb 16M QCD: 2, 3 and 4 jets (500 GeV< E T (j1) < 3000 GeV) AlpGen 9.4 × 10 4 fb 0.3M tt: tt + 0, 1 and 2 jets AlpGen 1.6 × 10 5 fb 5M bb: bb + 0, 1 and 2 jets AlpGen 8.8 × 10 7 fb 91M Z + jets: Z/γ(→ ll, νν) + 0, 1, 2 and 3 jets AlpGen 8.6 × 10 6 fb 13M W + jets: W ± (→ lν) + 0, 1, 2 and 3 jets AlpGen 1.8 × 10 7 fb 19M Z + tt: Z/γ(→ ll, νν) + tt + 0, 1 and 2 jets AlpGen 53 fb 0.6M Z + bb: Z/γ(→ ll, νν) + bb + 0, 1 and 2 jets AlpGen 2.6 × 10 3 fb 0.3M W + bb: W ± (→ all) + bb + 0, 1 and 2 jets AlpGen 6.4 × 10 3 fb 9M W + tt: W ± (→ all) + tt + 0, 1 and 2 jets AlpGen…”

Renormalization Group Analysis of Supersymmetric Particle Interactions

“…We show curves for both the one-loop and two-loop variation of M 2 /M 1 for two choices of tan β and µ, and see that, in the case of low tan β and large values of µ, contributions from two-loop terms and threshold corrections to the RGEs cause deviations of the gaugino mass ratio from α 2 /α 1 by as much as 10%. 1 We anticipate that increasing the splitting between the scalar and the gaugino/higgsino sector of the theory will drive this figure higher. Lastly, note that the correction introduced by moving to two-loop running is far smaller than that introduced by the thresholds, as a result of the large splitting between SUSY particles.…”

“…For our predictions to be accurate to two-loops, we must take full account of the non-degenerate SUSY mass spectrum by introducing particle thresholds into the oneloop RGEs. Once the various particles are decoupled from the theory, we must also take account of splitting between couplings that are equal in the SUSY limit [1].…”
