Standard conjecture D for matrix factorizations

open access: yesAdvances in Mathematics, 2020
We prove the non-commutative analogue of Grothendieck's Standard Conjecture D for the dg-category of matrix factorizations of an isolated hypersurface singularity in characteristic 0. Along the way, we show the Euler pairing for such dg-categories of matrix factorizations is positive semi-definite.

Uncertainties of the $$B\rightarrow D$$ B→D transition form factor from the D-meson leading-twist distribution amplitude

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
The $$B\rightarrow D$$ B→D transition form factor (TFF) $$f^{B\rightarrow D}_+(q^2)$$ f+B→D(q2) is determined mainly by the D-meson leading-twist distribution amplitude (DA) , $$\phi _{2;D}$$ ϕ2;D , if the proper chiral current correlation function is ...
