“…Third generation Yukawa coupling constants are highly affected by input value of tan β as shown in Equation (3). A detailed numerical analysis shows that high scale value of h t always decreases with input value on SUSY breaking scale m s in the range (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) TeV for low and high tan β = 25, 35, 40, 45, and 55. However, high scale values of h b and h τ behave in different patterns.…”

“…Neutrino physics has registered significant progress in recent years with the measurements of nonzero θ 13 [1][2][3] and the Dirac CP phase [4,5], thus indicating a possibility for a sizable CP violation in neutrino sector. The T2K team [5] has concluded with 3σ confidence level that the Dirac Phase δ CP lies somewhere between -3.41 and -0.03 for normal hierarchy (NH) and between -2.54 and -0.32 for inverted hierarchy (IH).…”

The paper addresses the effects of the variations of the SUSY breaking scale m s in the range (2-14) TeV on the three neutrino masses and mixings, in running the renormalization group equations (RGEs) for different input values of high energy seesaw scale M R , and in both normal and inverted hierarchical neutrino mass models. The present investigation is a continuation of the earlier works based on the variation of m s scale. Two approaches are adopted one after another—bottom-up approach for running gauge and Yukawa couplings from low to high energy scale, followed by the top-down approach from high to low energy scale for running neutrino parameters defined at high energy scale, along with gauge and Yukawa couplings. A self-complementarity relation among three mixing angles is also employed in the analysis and it is found to be stable under radiative correction. Significant effect due to radiative corrections on neutrino parameters with the variation of SUSY breaking scale m s is observed. For comparison of the results, variation of tan β for different M R is also considered.
