Mixed Hodge structures and renormalization in physics [PDF]
Communications in Number Theory and Physics, 2008 We relate renormalization in perturbative quantum field theory to the theory of limiting mixed Hodge structures using parametric representations of Feynman graphs.

Towards precision charm physics with a mixed action
Proceedings of The 39th International Symposium on Lattice Field Theory — PoS(LATTICE2022), 2022 We report on our first set of results for charm physics, using a mixed-action setup with maximally twisted valence fermions on CLS $N_f=2+1$ ensembles. This setup avoids the need of improvement coefficients to subtract $O(am_c)$ effects. The charm quark mass, $D$ and $D_s$ decay constants are computed on a subset of CLS ensembles, which allows to take ...

Physical Interpretation of Mixing Diagrams [PDF]
Journal of Geophysical Research: Atmospheres, 2018 AbstractType of mixing at cloud edges is often determined by means of mixing diagrams showing the dependence of normalized cube of the mean volume radius on the dilution level. The mixing diagrams correspond to the final equilibrium state of mixing between two air volumes.

A tmQCD mixed-action approach to flavour physics [PDF]
EPJ Web of Conferences, 2018 We discuss a mixed-action approach in which sea quarks are regularised using non-perturbatively O(a) improved Wilson fermions, while a fully-twisted tmQCD action is used for valence quarks. In this setup, automatic O(a) improvement is preserved for valence observables, apart from small residual O(a) effects from the sea. A strategy for matching sea and

Physical characteristics of mixed-species swarming colonies
Physical Review E, 2022 In nature, bacterial collectives typically consist of multiple species, which are interacting both biochemically and physically. Nonetheless, past studies on the physical properties of swarming bacteria were focused on axenic (single species) populations. In bacterial swarming, intricate interactions between the individuals lead to clusters, rapid jets

Charm mixing in the Standard Model and beyond [PDF]
, 2006 The motivation most often cited in searches for D0-anti-D0 mixing and CP-violation in charm system lies with the possibility of observing a signal from New Physics which dominates that from the Standard Model. We review recent theoretical predictions and

Physical range of majorana neutrino mixing parameters [PDF]
Physical Review D, 2008 If neutrinos are Majorana fermions, the lepton mixing parameter space consists of six mixing parameters: three mixing angles and three CP-odd phases. A related issue concerns the physical range of the mixing parameters. What values should these take so that all physically distinguishable mixing scenarios are realized?

Classical and quantum physics mix [PDF]
Nature, 1995 A neat way of talking of quantum and classical physics in the same language will be of interest in itself even if it does not avoid the need for a quantum theory of gravity; but that would be a huge extra.

B physics Beyond the Standard Model at One Loop: Complete Renormalization Group Evolution below the Electroweak Scale [PDF]
, 2017 General analyses of $B$-physics processes beyond the Standard Model require accounting for operator mixing in the renormalization-group evolution from the matching scale down to the typical scale of $B$ physics.
