Wilson Line Inflation
We present a general set-up for inflation in string theory where the inflaton field corresponds to Wilson lines in compact space in the presence of magnetic fluxes. T -dualities and limits on the value of the magnetic fluxes relate this system to the standard D-brane inflation scenarios, such as brane-antibrane inflation, D3/D7 brane inflation and different configurations of branes at angles. T...
متن کاملWarped Wilson Line DBI Inflation
We propose a novel inflationary scenario in string theory in which the inflaton field is aWilson line degree of freedom in the worldvolume of a probe Dp-brane, in a warped flux compactification. Kinetic terms for Wilson line fields on the world volume of a D-brane take a nonstandard DiracBorn-Infeld (DBI) form. Thus, we work in the framework of DBI inflation. This extends the original slow roll...
متن کاملWilson line breaking and gauge coupling unification .
We estimate the effect of threshold corrections coming from Wilson lines to gauge coupling unification in the weakly coupled heterotic string with orbifold compactification. By expressing the corrections in terms of an effective field theory calculation we are able to estimate the minimal threshold corrections in a realistic model without constructing the full string theory. Using this we show ...
متن کاملWavy Wilson Line and AdS / CFT
Wilson loops which are small deviations from straight, infinite lines, called wavy lines, are considered in the context of the AdS/CFT correspondence. A single wavy line and the connected correlation function of a straight and wavy line are considered. It is argued that, to leading order in “waviness”, the functional form of the loop is universal and the coefficient, which is a function of the ...

We introduce a Wilson line distribution function W τ (v) to study gluon saturation at small Feynman x F , or large τ = ln(1/x F ). This new distribution can be obtained from the distribution Wτ (α) of the Color Glass Condensate model and the JIMWLK renormalization group equation. W τ (v) is physically more relevant, and mathematically simpler to deal with because of unitarity of the Wilson line...
