The GeoModel tool suite for detector description [PDF]
EPJ Web of Conferences, 2021 The GeoModel class library for detector description has recently been released as an open-source package and extended with a set of tools to allow much of the detector modeling to be carried out in a lightweight development environment, outside of large ...

Geometry of Lines on a Cubic Four-Fold
International Mathematics Research Notices, 2023 Abstract For a general cubic four-fold $X\subset {\mathbb {P}}^5$ with Fano scheme of lines $F$, we prove a number of properties of the universal family of lines $I\to F$ and various subloci. We first describe the moduli and ramification theory of the genus four fibration $p:I\to X$ and explore its relation to a birational model of $F ...

World-line geometry probed by fast spinning particle [PDF]
, 2014 Interaction of spin with electromagnetic field yields an effective metric along the world line of spinning particle. If we insist to preserve the usual special-relativity definitions of time and distance, critical speed which spinning particle can not ...

Quantum Riemannian geometry and particle creation on the integer line [PDF]
Classical and quantum gravity, 2018 We construct noncommutative or ‘quantum’ Riemannian geometry on the integers as a lattice line with its natural 2-dimensional differential structure and metric given by arbitrary non-zero edge square-lengths .

Kinematic Differential Geometry of a Line Trajectory in Spatial Movement
Axioms, 2023 This paper investigates the kinematic differential geometry of a line trajectory in spatial movement. Specifically, we provide a theoretical expression of inflection line congruence, which is the spatial equivalent of the inflection circle of planar ...

Kinematic Geometry of a Timelike Line Trajectory in Hyperbolic Locomotions
Axioms, 2023 This study utilizes the axodes invariants to derive novel hyperbolic proofs of the Euler–Savary and Disteli formulae. The inflection circle, which is widely recognized, is situated on the hyperbolic dual unit sphere, in accordance with the principles of ...
