A bstract We use the F-theoretic engineering of four-dimensional rank-one superconformal field theories to provide a geometric understanding phenomenon supersymmetry enhancement along RG flow, recently observed by Maruyoshi and Song. In this context, superpotential deformations responsible for such flows are interpreted as T-brane backgrounds encoded in geometry elliptically-fibered fourfolds. formulate simple algebraic criterion select all supersymmetry-enhancing and, without any maximization process, derive main features corresponding $$ \mathcal{N} <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>N</mml:mi> </mml:math> = 2 infrared.
