CP violation in three-body B decays: a model ansatz

Journal of High Energy Physics, 2020
The mechanism of CP violation remains one of the puzzles in particle physics. Key to understanding this phenomenon are nonleptonic B decays, especially multibody decays which exhibit large CP asymmetries in various regions of phase space.

Automorphisms of Real 4 Dimensional Lie Algebras and the Invariant Characterization of Homogeneous 4-Spaces [PDF]

, 2002
The automorphisms of all 4-dimensional, real Lie Algebras are presented in a comprehensive way. Their action on the space of $4\times 4$, real, symmetric and positive definite, matrices, defines equivalence classes which are used for the invariant ...

Conformal invariance and 2𝐷 statistical physics [PDF]

Bulletin of the American Mathematical Society, 2008
A number of two-dimensional models in statistical physics are conjectured to have scaling limits at criticality that are in some sense conformally invariant. In the last ten years, the rigorous understanding of such limits has increased significantly.

Higgs boson pair production at NNLO in QCD including dimension 6 operators

Journal of High Energy Physics, 2017
In this paper we present the computation of the Higgs boson pair production cross section, both inclusive as well as differential on the invariant mass distribution, at next-to-next-to-leading order (NNLO) in QCD including effects of new physics beyond ...

Symmetry as a source of hidden coherent structures in quantum physics: general outlook and examples

, 1998
A general algebraic approach, incorporating both invariance groups and dynamic symmetry algebras, is developed to reveal hidden coherent structures (closed complexes and configurations) in quantum many-body physics models due to symmetries of their ...

Some new invariant solutions of nonlinear fifth order partial differential equation via Lie approach

Partial Differential Equations in Applied Mathematics
In this paper, the classical Lie symmetry analysis of (1+3) dimensional perturbed Zakharov–Kuznetsov (pZK) equation has been studied. We present a thorough classification of Lie point symmetries for pZK equation.

An Arena for Model Building in the Cohen-Glashow Very Special Relativity

, 2008
The Cohen-Glashow Very Special Relativity (VSR) algebra [arXiv:hep-ph/0601236] is defined as the part of the Lorentz algebra which upon addition of CP or T invariance enhances to the full Lorentz group, plus the space-time translations.

High-dimensional and permutation invariant anomaly detection

SciPost Physics
Methods for anomaly detection of new physics processes are often limited to low-dimensional spaces due to the difficulty of learning high-dimensional probability densities. Particularly at the constituent level, incorporating desirable properties such as
