Gauge Coupling Unification: Strings versus SUSY-GUTs
Standard (level one) heterotic string models with standard model gauge group predict the unification of SU(3) and SU(2) gauge couplings whereas the U(1) factor is unified modulo an unknown normalization factor k1. On the other hand the unification mass is known. I argue that this situation is quite analogous (though opposite) to that in SUSYGUTs in which the U(1) normalization is known (k1 = 5/...
متن کاملSplit-SUSY versus SUSY GUTs
The gauge coupling unification is one of main motivations in the split-SUSY scenario, and the existence of the grand unified theories (GUTs) is assumed. We examine how to realize split-SUSY mass spectrum in the context of GUTs and find that the construction of split-SUSY GUTs is by no means straightforward. With R-symmetry breaking sources in the GUT sector, GUT particles play a role of the mes...
متن کاملGauge Coupling Unification, SUSY Scale and Strong Coupling Running
Abstract. The apparent unification of gauge couplings around 1016 GeV is one of the strong arguments in favor of Supersymmetric extensions of the Standard Model (SM). In this contribution two new analyses of the gauge coupling running, the latter using in contrast to previous studies not data at the Z peak but at LEP2 energies, are presented. The generic SUSY scale in the more precise novel app...
متن کاملKaluza-Klein decomposition and gauge coupling unification in orbifold GUTs
We discuss Kaluza-Klein (KK) decomposition in 5-dimensional (5D) field theories with orbifold compactification. Kinetic terms localized at orbifold fixed points, which are inevitably present in any realistic model, modify the standard KK mass spectrum and interactions of KK modes. This, in turn, can significantly affect phenomenology of the orbifold models. As an example, we discuss gauge coupl...
متن کاملUnification Beyond GUTs : Gauge - Yukawa Unification ∗
Gauge-Yukawa Unification (GYU) is a renormalization group invariant functional relation among gauge and Yukawa couplings which holds beyond the unification point in Grand Unified Theories (GUTs). We present here various models where GYU is obtained by requiring the principles of finiteness and reduction of couplings. We examine the consequences of these requirements for the low energy parameter...
