Light-cone sum rules for B → K π form factors and applications to rare decays [PDF]
Journal of High Energy Physics, 2019 We derive a set of light-cone sum rules relating the hadronic form factors relevant for B → Kπℓ+ℓ− decays to the B-meson light-cone distribution amplitudes (LCDAs).

Gravitational form factors within light-cone sum rules at leading order [PDF]
Physical Review D, 2019 We develop an approach based on the light-cone sum rules at the leading order of $\alpha_S$ to calculate the gravitational form factors $A(t)$ and $B(t)$ for the valence quark combinations in nucleon.

Factorization theorem relating Euclidean and light-cone parton distributions [PDF]
Physical Review D, 2018 In a large momentum nucleon state, the matrix element of a gauge-invariant Euclidean Wilson line operator accessible from lattice QCD can be related to the standard light-cone parton distribution function through the large-momentum effective theory ...

Light-cones, almost light-cones and almost-complex light-cones [PDF]
General Relativity and Gravitation, 2017 We point out an unusual relationship among a variety of null geodesic congruences; (a) the generators of ordinary light-cones and (b) certain (related) shear-free but twisting congruences in Minkowski Space-time as well as (c) asymptotically shear-free null geodesic congruences that exist in the neighborhood of Penrose's Scri in Einstein or Einstein ...

Light-cone gauge massive and partially-massless fields in AdS(4)
Physics Letters B, 2023 Using light-cone gauge approach, bosonic and fermionic massive and partially-massless fields in AdS(4) space are considered. For such fields, light-cone gauge action is presented.

Quantum Chromodynamics and Other Field Theories on the Light Cone [PDF]
, 1997 We discuss the light-cone quantization of gauge theories as a calculational tool for representing hadrons as QCD bound-states of relativistic quarks and gluons, and also as a novel method for simulating quantum field theory on a computer.
