… It is extremely useful to have specific motivation to shape the goals of future colliders. 2 PreHiggs Guarantee Planning for colliders was simple following the discovery of W/Z bosons: Violation of unitarity in VV scattering Standard Model breaks down parametrically near weak scale
WEAK SCALE
, 1990
"... One of the fundamenta1 constants of nature is the baryon asymmetry of the universe the ratio of the number of baryons to the entropy. This constant is about lo l1. In baryonnumber conserving theories, this was just an initial condition. With the advent of grand unified theories (GUTS), baryon num ..."

is the electroweak phase transition, described by the standard model, which posses all the necessary ingredients for baryogenesis. Anomalous baryonnumber violation in weak interactions becomes large at high temperatures, which offers the prospect of creating the asymmetry with the standard model or minimal
The Weak Scale from BBN
"... The measured values of the weak scale, v, and the first generation masses, mu,d,e, are simultaneously explained in the multiverse, with all these parameters scanning independently. At the same time, several remarkable coincidences are understood. Small variations in these parameters away from thei ..."

Weakscale supersymmetry: theory and practice
"... These lectures contain an introduction to the theory and practice of weakscale supersymmetry. They begin with a discussion of the hierarchy problem and the motivation for weakscale supersymmetry. They continue by developing the coset approach to superfields. They use superfield techniques to const ..."

From weakscale observables to leptogenesis
 JHEP
, 2003
"... Thermal leptogenesis is an attractive mechanism for generating the baryon asymmetry of the Universe. However, in supersymmetric models, the parameter space is severely restricted by the gravitino bound on the reheat temperature TRH. For hierarchical light neutrino masses, it is shown that thermal le ..."

leptogenesis can work when TRH ∼ 10 9 GeV. The lowenergy observable consequences of this scenario are BR(τ → ℓγ) ∼ 10 −8 − 10 −9. For higher TRH, thermal leptogenesis works in a larger area of parameter space, whose observable consequences are more ambiguous. A parametrisation of the seesaw in terms of weakscale
The hierarchy problem and new dimensions at a millimeter
, 2008
"... We propose a new framework for solving the hierarchy problem which does not rely on either supersymmetry or technicolor. In this framework, the gravitational and gauge interactions become united at the weak scale, which we take as the only fundamental short distance scale in nature. The observed wea ..."

A large mass hierarchy from a small extra dimension
, 1999
"... We propose a new higherdimensional mechanism for solving the hierarchy problem. The weak scale is generated from a large scale of order the Planck scale through an exponential hierarchy. However, this exponential arises not from gauge interactions but from the background metric (which is a slice of ..."

The WeakScale Hierarchy and Discrete Symmetries
, 1995
"... In the underlying Planck scale theory we introduce a certain type of discrete symmetry, which potentially brings the stability of the weakscale hierarchy under control. Under the discrete symmetry the µproblem and the tadpole problem can be solved simultaneously without relying on some finetuning ..."

Solving the cosmological moduli problem with weak scale inflation
"... Many models of supersymmetry breaking involve particles with weak scale mass and Planck mass suppressed couplings. Coherent production of such particles in the early universe destroys the successful predictions of nucleosynthesis. We show that this problem may be solved by a brief period of weak sca ..."

Chiral models of weak scale supersymmetry
 Nucl. Phys. B
, 2000
"... I discuss supersymmetric extensions of the Standard Model containing an extra U(1) ′ gauge symmetry which provide a solution to the µproblem and at the same time protect the proton from decaying via dimension 4 operators. Moreover, all fields are protected by chirality and supersymmetry from acquir ..."
