Describing the Global Gravity Field of Mars With Lithospheric Flexure and Deep Mantle Flow
Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract The volcanic complex Tharsis Region on Mars is known for its numerous volcanoes on top of the crust, elevated topography (doming), and a long‐wavelength gravity anomaly correlated with the region. Flexural modeling of the lithosphere has commonly been used to understand the relationship between observed topography, crustal structure, and ...

On-shelļ methods for perturbative QCD [PDF]
, 2006 We present new on-shell techniques for the calculation of colour ordered helicity amplitudes in QCD. We review the methods of on-shell recursion and the MHV rules before applying them to tree-level processes within the Standard Model.

Four-loop QCD cusp anomalous dimension at small angle
Journal of High Energy Physics, 2022 We calculate the small angle expansion of the four-loop QCD cusp anomalous dimension. As a byproduct of our calculation, we also obtain the four-loop anomalous dimension of the heavy-quark field in HQET.

Annalen der Physik, Volume 538, Issue 1, January 2026.The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

On the gauge-invariance of SCET beyond leading power
Journal of High Energy Physics, 2023 We point out that the gauge-invariance of the subleading Lagrangian of soft-collinear effective theory is realised in an intricate way through momentum-conservation violating contributions.

Mid‐Infrared Free‐Space Optical Communications: Technologies, Demonstrations and Future Directions
IET Optoelectronics, Volume 20, Issue 1, January/December 2026.Free‐space optical (FSO) communication is increasingly extending beyond the near‐infrared to the mid‐wave infrared (MWIR) and long‐wave infrared (LWIR) regions, which offer reduced turbulence, scattering and absorption for more robust links. This review summarises recent advances in MWIR/LWIR FSO technologies, including quantum cascade lasers, lithium ...

An Overview of Scale Invariance in Proton Structure With Holographic Insights
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.The concept of self‐similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).
