<div style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);"><font size="2"><span style="font-size: 12pt;">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.</span></font><br>
