Electroweak Evolution Equations
Enlarging a previous analysis, where only fermions and transverse gauge bosons were taken into account, we write down infrared-collinear evolution equations for the Standard Model of electroweak interactions computing the full set of splitting functions. Due to the presence of double logs which are characteristic of electroweak interactions (Bloch-Nordsieck violation), new infrared singular spl...
متن کاملTowards collinear evolution equations in electroweak theory.
We investigate collinear factorization in electroweak radiative corrections to hard inclusive processes at the TeV scale. Because of the uncanceled double logs found previously, we find a factorization pattern which is qualitatively different from the analogous one in QCD. New types of splitting functions emerge which are needed to describe the initial beam charges and are dependent on an infra...
متن کاملEvolution Equations in the Electroweak Sector of the Standard Model
Energy-growing electroweak corrections in the Standard Model are potentially relevant for LHC physics, for Next generation of Linear Colliders (NLCs) and for ultrahigh energy cosmic rays. I present here the results of recent work in which electroweak evolution equations (the analogous of DGLAP equations in QCD) have been derived. The main features of these effects, mainly related to the fact th...
متن کاملInstability and subsequent evolution of electroweak bubbles.
⋆ e-mail: [email protected]. † SSC Fellow ‡ e-mail: [email protected] § Presidential Young Investigator and Sloan Foundation Fellow Bubbles in a first-order electroweak phase transition are nucleated with radii R0 and expand with velocity v. If v is subsonic, a bubble becomes unstable to non-spherical perturbations when its radius is roughly 104 R0. These perturbations accelerate the ...
متن کاملEvolution equations
Let X,Y be normed spaces. The set of bounded linear operators is noted as L(X,Y ). Let now D = D(A) ⊂ X be a linear subspace, and A : D −→ Y a linear (not necessarily bounded!) operator. Notation: (A,D(A)) : X −→ Y Definition: G(A) := {(x,Ax) |x ∈ D} is called the graph of A. Obviously, G(A) is a linear subspace of X × Y . The linear operator A is called closed if G(A) is closed in X × Y . The ...
