Baikov representations, intersection theory, and canonical Feynman integrals

Journal of High Energy Physics, 2022
The method of canonical differential equations is an important tool in the calculation of Feynman integrals in quantum field theories. It has been realized that the canonical bases are closely related to d-dimensional d log-form integrands. In this work,

Interplay Between MW, ΩCDMh2, and (g − 2)μ in Flavor Symmetry–Based Supersymmetric Models

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
We study the phenomenological implications of the minimal supersymmetric standard model (MSSM) augmented by a nonabelian flavor symmetry labeled as sMSSM. Incorporating this flavor symmetry allows for a significant reduction in the original plethora of free parameters present in the MSSM, ultimately reducing them down to just seven in sMSSM.

Theoretical Uncertainties in Electroweak Boson Production Cross Sections at 7, 10, and 14 TeV at the LHC

, 2010
We present an updated study of the systematic errors in the measurements of the electroweak boson cross-sections at the LHC for various experimental cuts for a center of mass energy of 7, 10 and 14 TeV.

How to Experimentally Determine the Influence of the Weak Nuclear Force in Promoting Molecular Chirality via Heavy–Metal Promoted Autocatalytic Synthesis of Amino Acids

ChemistrySelect, Volume 9, Issue 36, September 25, 2024.
An experimental test of the impact of the parity non‐conserving weak nuclear interaction on the chirality of a nascent chiral carbon center is proposed. It is shown that catalysis by heavy elements could yield observable chiral preferences within a time span of weeks to months when heavy metals are used to promote amino acid synthesis via an ...

Some recent results for SU(3) and octonions within the geometric algebra approach to the fundamental forces of nature

Mathematical Methods in the Applied Sciences, Volume 47, Issue 3, Page 1471-1491, February 2024.
Different ways of representing the group SU(3)$$ SU(3) $$ within a Geometric Algebra approach are explored. As part of this, we consider characteristic multivectors for SU(3)$$ SU(3) $$ and how these are linked with decomposition of generators into commuting bivectors. The setting for this work is within a 6d Euclidean Clifford Algebra.

NLO EW and QCD corrections to polarised same-sign WW scattering at the LHC

Journal of High Energy Physics
We present the first calculation of same-sign WW scattering at the LHC in the fully leptonic decay channel including the modelling of polarisation for intermediate electroweak bosons and radiative corrections up to NLO EW+QCD accuracy.

Top-quark couplings to TeV resonances at future lepton colliders [PDF]

, 2000
We study the processes $W_L W_L \to t \bar t$ and $W_L Z_L \to t\bar b (\bar t b)$ at future lepton colliders as probes of the couplings of the top quark to resonances at the TeV scale.

Limits on Dark Photons, Scalars, and Axion‐Electromagnetodynamics with the ORGAN Experiment

Annalen der Physik, Volume 536, Issue 1, January 2024.
The nature of dark matter is one of the biggest mysteries in the Universe. ORGAN is an experiment which seeks to understand dark matter by figuring out what it is made of. In this article, the current sensitivity of ORGAN to various promising dark matter candidates is presented, and the future sensitivity is projected.

Complete NLO corrections to off-shell t t ¯ Z $$ \textrm{t}\overline{\textrm{t}}\textrm{Z} $$ production at the LHC

Journal of High Energy Physics, 2023
Measuring precisely top-pair-associated processes at hadron colliders will become possible with the upcoming LHC running stages. The increased data statistics will especially enable differential measurements leading to an improved characterisation of ...
