A Short Review on Recent Developments in TMD Factorization and Implementation

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019
In the latest years the theoretical and phenomenological advances in the factorization of several collider processes using the transverse momentum dependent distributions (TMD) have greatly increased. I attempt here a short resume of the newest developments discussing also the most recent perturbative QCD calculations. The work is not strictly directed

IR‐Improved DGLAP‐CS Theory

Advances in High Energy Physics, Volume 2008, Issue 1, 2008., 2008
We show that it is possible to improve the infrared aspects of the standard treatment of the DGLAP‐CS evolution theory to take into account a large class of higher‐order corrections that significantly improve the precision of the theory for any given level of fixed‐order calculation of its respective kernels.

Ultraviolet phenomena in AdS self-interacting quantum field theory

Journal of High Energy Physics, 2018
We study the one-loop corrections to the four-point function in the Anti de Sitter space-time for a ϕ 4 field theory. Our calculation shows the existence of non-local counterterms which however respect the AdS isometry.

Hot accelerated qubits: decoherence, thermalization, secular growth and reliable late-time predictions

Journal of High Energy Physics, 2020
We compute how an accelerating qubit coupled to a scalar field — i.e. an Unruh-DeWitt detector — evolves in flat space, with an emphasis on its late-time behaviour.

The swampland conjecture and the Higgs expectation value

Journal of High Energy Physics, 2018
The recently proposed de Sitter swampland conjecture excludes local extrema of a scalar potential with a positive energy density in a low energy effective theory.

Hot cosmic qubits: late-time de Sitter evolution and critical slowing down

Journal of High Energy Physics, 2020
Temporal evolution of a comoving qubit coupled to a scalar field in de Sitter space is studied with an emphasis on reliable extraction of late-time behaviour.

Renormalized holographic subregion complexity under relevant perturbations

Journal of High Energy Physics, 2020
We construct renormalized holographic entanglement entropy (HEE) and subregion complexity (HSC) in the CV conjecture for asymptotically AdS4 and AdS5 geometries under relevant perturbations.

The Abelian Higgs model under a gauge invariant looking glass: exploiting new Ward identities for gauge invariant operators and the Equivalence Theorem

Journal of High Energy Physics, 2021
The content of two additional Ward identities exhibited by the U(1) Higgs model is exploited. These novel Ward identities can be derived only when a pair of local composite operators providing a gauge invariant setup for the Higgs particle and the ...

Exact renormalization of the photino mass in softly broken N $$ \mathcal{N} $$ = 1 SQED with N f flavors regularized by higher derivatives

Journal of High Energy Physics, 2017
We consider the softly broken N $$ \mathcal{N} $$ = 1 supersymmetric electrodynamics, regularized by higher derivatives. For this theory we demonstrate that the renormalization of the photino mass is determined by integrals of double total derivatives in

Wilsonian renormalisation of CFT correlation functions: field theory

Journal of High Energy Physics, 2017
We examine the precise connection between the exact renormalisation group with local couplings and the renormalisation of correlation functions of composite operators in scale-invariant theories.
