<p class="MsoNormal"><b><u>Alexey Vladimirov</u></b> (Regensburg University) will speak about "Transverse Momentum Dependent factorization beyond the leading power"</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><b><u>Abstract</u></b>:</p>
<p class="MsoNormal">Transverse momentum dependent (TMD) factorization is an important tool for description of differential cross-sections and for the exploration of hadron's intrinsic structure. The leading power TMD factorization is known detailly, while
power corrections remain almost unexplored. In the talk, I present the novel approach to the TMD factorization -- transverse momentum dependent operator expansion. This approach is methodologically similar to the light-cone operator product expansion and allows
for a systematic computation of power corrections to TMD factorization. In particular, it gives rise to the definition of TMD-twist, which sorts TMD operators with respect to their evolution properties and provides a certain decomposition of power corrections
into kinematic and genuine. As a demonstration of the approach, I present the computation of next-to-leading power correction at next-to-leading order in perturbative series and discuss properties of power suppressed TMD distributions.</p>
