conjugacy in relatively extra-large artin groups
in this work we consider conjugacy of elements and parabolic subgroups in details, in a new class of artin groups, introduced in an earlier work, which may contain arbitrary parabolic subgroups. in particular, we find algorithmically minimal representatives of elements in a conjugacy class and also an algorithm to pass from one minimal representative to the others.
متن کاملLarge hierarchy from extra dimensions
We argue that the familiar gauge hierarchy between the fundamental Planck scale MP l and the electroweak scaleMW , can be naturally explained in higher dimensional theories with relatively large radii (Rc > 1/MP l) extra dimensions. In particular, we show that it is possible that the electroweak Higgs mass at high energies is of the order of MP l, but radiative corrections drive it to an infrar...
متن کاملLarge Extra Dimensions from a Small Extra Dimension
Models with extra dimensions have changed our understanding of the hierarchy problem. In general, these models explain the weakness of gravity by diluting gravity in a large bulk volume, or by localizing the graviton away from the standard model. In this paper, we show that the warped geometries necessary for the latter scenario can naturally induce the large volumes necessary for the former. W...
متن کاملPhenomenology of Supersymmetric Large Extra Dimensions
We study the phenomenology of a supersymmetric bulk in the scenario of large extra dimensions. The virtual exchange of gravitino KK states in selectron pair production in polarized e+e− collisions is examined. The leading order operator for this exchange is dimension six, in contrast to that of graviton KK exchange which induces a dimension eight operator at lowest order. Some kinematic distrib...
متن کاملLocal Lagrangian for Exponentially Large Extra Dimensions
We write an explicit local action for a large extra dimensions stabilization scenario due to Arkani-Hamed, Hall, Smith and Weiner (AHSW). Our action allows the AHSW proposal to be generalized to non-Poincaré invariant configurations, supersymmetric extensions, quantum effective field theory, and cosmological scenarios. The central step in constructing the action is working in terms of the four ...
