Geometric algebra provides a natural extension of vector geometry that unifies rotations, boosts, and spinors within a single geometric framework. Starting from rotations in physical space, rotors emerge as the fundamental objects encoding orientation and transformation. This structure extends seamlessly to spacetime, where Lorentz boosts appear on equal geometric footing with spatial...

The geometric Algebra of Physical Space (APS) has recently been used to explore the Constructive Standard Model (CSM) of particle physics. Namely, the spinor formalism of the APS was rigorously tied to the CSM via a tool called the Scattering Algebra (SA). Significant insights were discovered: That the CSM's spin spinors (massive helicity spinors) are matrix representations of the APS'...

In this talk, I present a dispersive framework for unitarizing electroweak amplitudes using continuous spectral densities. Assuming fixed-angle UV softness, analyticity, crossing symmetry, and unitarity leads to sum rules that relate the infrared electroweak amplitude to positive spectral moments. For the $WWWW$ scattering process, the amplitude grows as $E^2$ if only gauge-boson contributions...

In this talk, I will present recent advancements in mathematical and cosmological frameworks, drawing from my key studies. I will introduce functorial methods in Functors of Actions Theories (FAT), bridging mathematical rigor with cosmological phenomena, by predicting actionions [1,2]. Noticing the need of advanced math, I will introduce the exploration of novel tensor-based approaches from...

General Relativity (GR) is the classical interpretation of gravitational interaction. Equivalently, GR can be represented as an effective field theory (EFT) of the non-trivial self-interacting theory of a massless spin-2 particle. The Planck mass sets the high-energy cutoff, which is where we expect to see the effects of quantum gravity. Various modifications to gravity significantly lower the...

The structure of chiral anomalies in brane world models presents subtle but important features. While the divergence of a 5D current has long been known to localize to end-of-the-world branes and distribute evenly between them, this picture breaks down when branes are hidden by horizons or replaced by soft-wall geometries. We demonstrate that in models motivated by the AdS/CFT correspondence —...

We provide a detailed review and extension of compact, exactly solvable, pure Abelian and non-Abelian gauge theories in 1+1 dimensions, which have many similarities to (3+1)D pure Yang-Mills like confinement and a theta term. We focus on the U(1), SU(N) and SU(N)/ZN gauge groups. For the Abelian (1+1)D QED theory, we present a non-relativistic quantum mechanics calculation of the electric...

It is well-known that the quantum interference pattern in a two-slit experiment cannot be reduced to a sum of two single-slit patterns. However, as first noted by Rafael Sorkin, even when one has a variant of such an experiment consisting of three or more slits, quantum mechanics predicts that the resulting interference pattern can be reduced to a sum of two-slit patterns. Therefore, quantum...

We study extended warped extra-dimensional models in which gravity propagates to a deep infrared brane with warped scale $\Lambda_{IR} \sim \mathcal{O}(\mathrm{MeV})$, leading to a dense KK graviton tower with MeV-scale spacing. We present a DUNE-motivated model realization of the photon portal to this tower. The visible electroweak gauge sector extends to an intermediate GeV brane, and...

Asymptotic velocity domination (AVD) posits that when back-propagated to the Big Bang generic cosmological spacetimes solve a drastically simplified version of the Einstein field equations, where all dynamical spatial gradients are absent (similar as in the Belinski-Khalatnikov-Lifshitz scenario). Conversely, a solution can in principle be reconstructed from its behavior near the Big Bang....

Recent work has highlighted a surprising connection between quantum information and high energy physics.In this talk, I will discuss how symmetry and general consistency conditions constrain the entanglement structure of scattering amplitudes, largely independent of detailed dynamics.In Yang–Mills theory, symmetry alone strongly constrains this structure, leading to universal entanglement...

Quantum forces are long-range interactions arising from vacuum fluctuations of mediator fields. Conventionally, they are computed via one-loop Feynman diagrams. In this talk, I present a novel framework that instead directly evaluates the mediator field's quantum fluctuations by solving its quantized equation of motion with appropriate boundary conditions. This approach extends beyond the Born...

Splitting functions are the factorized forms of collinear dynamics in perturbative QCD and are central ingredients in parton shower models, whose precision is crucial for finding and understanding new physics in collider events. We present a compact form of the massive 1→3 tree-level QCD splitting functions, obtained without reference to soft or quasi-collinear limits. The triple-collinear...

Without fine-tuning, it is difficult to maintain the utility of the axion as candidate solution to the strong CP problem when it is embedded in UV models due to additional interactions that spoil the IR phenomenology. Anson Hook has presented a model where the axion potential is naturally exponentially suppressed through its interactions with N copies of the same fermionic sector. Although...
