Analytic structure in the coupling constant plane in perturbative QCD
, 2003 We investigate the analytic structure of the Borel-summed perturbative QCD amplitudes in the complex plane of the coupling constant. Using the method of inverse Mellin transform, we show that the prescription dependent Borel-Laplace integral can be cast,

|Vub| determination and testing of lepton flavour universality in semileptonic Bc → D(∗) decays
Journal of High Energy Physics, 2020 In light of prospects for measurements of B c → D (∗) lv decays in the upcoming Upgrade II of the LHC, we show that by using calculated B c → D (∗) form factors a competitive extraction of the |V ub | CKM matrix element from the B c → Dμ v ¯ μ $$ {B}_c\

Reconstructing S-matrix Phases with Machine Learning
Journal of High Energy PhysicsAn important element of the S-matrix bootstrap program is the relationship between the modulus of an S-matrix element and its phase. Unitarity relates them by an integral equation.

Revisiting Coleman-de Luccia transitions in the AdS regime using holography
Journal of High Energy Physics, 2021 Coleman-de Luccia processes for AdS to AdS decays in Einstein-scalar theories are studied. Such tunnelling processes are interpreted as vev-driven holographic RG flows of a quantum field theory on de Sitter space-time.

Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

Emergent Gauge Fields and Their Nonperturbative Effects in Correlated Electrons [PDF]
Modern Physics Letters B, 2015 The history of modern condensed matter physics may be regarded as the competition and reconciliation between Stoner’s and Anderson’s physical pictures, where the former is based on momentum–space descriptions focusing on long wave-length fluctuations while the latter is based on real-space physics emphasizing emergent localized excitations.

Stellar Physics and General Relativity
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT The general theory of relativity is currently established as the most precise theory of gravity supported by observations, and its application is diverse ranging from astronomy to cosmology, while its application to astrophysics has been restricted only to compact stars due to the assumption that the Newtonian approximation is sufficient for ...

How to define the moving frame of the Unruh-DeWitt detector on manifolds
Journal of High Energy PhysicsThe physical phenomena seen by an observer are defined for a local inertial system that is subjective to the observer. Such a coordinate system is called a “moving frame” because it changes from time to time.
