Split Supersymmetry in Unified Models
In the context of split supersymmetry, the gaugino mass spectrum seems to be very important to satisfy the dark matter content of the universe and the gauge coupling unification. In this paper, we have considered various sources of gaugino masses in the context of unified models. We show that the gaugino mass spectrum varies in different unification pictures. In the context of SU(5), we have fo...
متن کاملSplit Principles, Large Cardinals, Splitting Families and Split Ideals
We introduce split principles and show that their negations provide simple combinatorial characterizations of large cardinal properties. As examples, we show how inaccessiblity, weak compactness, subtlety, almost ineffability and ineffability can be characterized. Two-cardinal versions of these principles allow us to characterize when the two-cardinal versions of these properties hold: when κ i...
متن کاملRepresentative Families: A Unified Tradeoff-Based Approach
LetM=(E, I) be a matroid, and let S be a family of subsets of size p of E. A subfamily Ŝ ⊆ S represents S if for every pair of sets X ∈S and Y ⊆E\X such that X∪Y ∈ I, there is a set X̂ ∈ Ŝ disjoint from Y such that X̂∪Y ∈I. In this paper, we present a fast computation of representative families for uniform matroids. We use our computation to develop deterministic algorithms that solve k-Partial C...
متن کاملA unified approach to recognize squares of split graphs
The square of a graph G, denoted by G, is obtained from G by putting an edge between two distinct vertices whenever their distance is two. Then G is called a square root of G. Deciding whether a given graph has a square root is known to be NP-complete, even if the root is required to be a split graph, that is, a graph in which the vertex set can be partitioned into a stable set and a clique. We...
متن کاملOn Families of Split Cuts that Can Be Generated Efficiently
Split cuts represent the most widely used class of cutting planes currently employed by state-of-the-art branch-and-cut solvers for mixed integer linear programming. Rank-1 cuts often have better numerical properties than higher rank cuts. In this paper, we study several heuristics to generate new families of strong rank-1 split cuts, by considering integer linear combinations of the rows of th...
