Porphyrin‐Geländer–Helical Conjugated Banister Type Porphyrin Dyads
Chemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.Porphyrin arrays go chiral–A porphyrin Geländer macrocycle represents the intriguing prototype architecture of helically chiral butadiyne‐linked porphyrin arrays. This study combines synthetic, spectroscopic, and computational methods to shed light on its structure, chiroptical properties, and tunability, highlighting its promise for advancing ...

, 2004 We propose a framework for the implementation of a subtraction formalism at NNLO in QCD, based on an observable- and process-independent cancellation of infrared singularities. As a first simple application, we present the calculation of the contribution

High Entropy Wide‐Bandgap Borates with Broadband Luminescence and Large Nonlinear Optical properties
Advanced Functional Materials, Volume 36, Issue 35, 30 April 2026.High‐entropy rare‐earth borates exhibit excellent nonlinear optical and broadband luminescence properties arising from multi‐component doping, chemical disorder, increased configurational entropy, and increased lattice and electronic anharmonicity. This formulation enabled us to obtain a large, environmentally stable single crystal with 3X higher laser‐

Momentum Conservation at Small x [PDF]
, 1995 We discuss how momentum conservation is implemented in perturbative computations based on expansions of anomalous dimensions appropriate at small $x$. We show that for any given choice of $F_2$ coefficient functions there always exists a factorization ...

Symmetric ϵ- and (ϵ + 1/2)-forms and quadratic constraints in “elliptic” sectors.
Journal of High Energy Physics, 2018 Within the differential equation method for multiloop calculations, we examine the systems irreducible to ϵ-form. We argue that for many cases of such systems it is possible to obtain nontrivial quadratic constraints on the coefficients of ϵ-expansion of

Automation of electroweak corrections for LHC processes [PDF]
, 2015 For the Run 2 of the LHC next-to-leading order electroweak corrections will play an important role. Even though they are typically moderate at the level of total cross sections they can lead to substantial deviations in the shapes of distributions.

Mass dependence of Higgs production at large transverse momentum
Journal of High Energy Physics, 2017 The transverse momentum distribution of the Higgs at large P T is complicated by its dependence on three important energy scales: P T , the top quark mass m t , and the Higgs mass m H .
