Weyl-invariant Einstein-Cartan gravity: unifying the strong CP and hierarchy puzzles [PDF]

Journal of High Energy Physics
We show that the minimal Weyl-invariant Einstein-Cartan gravity in combination with the Standard Model of particle physics contains just one extra scalar degree of freedom (in addition to the graviton and the Standard Model fields) with the properties of

Dressing vs. Fixing: On How to Extract and Interpret Gauge-Invariant Content [PDF]

Foundations of physics
There is solid consensus among physicists and philosophers that, in gauge field theory, for a quantity to be physically meaningful or real, it must be gauge-invariant.

On interpolating anomalous dimension of twist-two operators with general spins

Journal of High Energy Physics, 2019
We study non-perturbative interpolating functions to probe the physics of anomalous dimensions associated with twist-two operators in N = 4 $$ \mathcal{N}=4 $$ SYM of finite and infinite spin.

Unitarity Triangles and the Search for New Physics [PDF]

, 2002
Assuming that the Kobayashi-Maskawa mechanism gives the dominant contribution to CP violation at low energies, we propose a novel way of testing the flavour sector of the Standard Model which has the potencial for discovering New Physics.

Invariance Testing of the Disablement in the Physically Active Scale [PDF]

Journal of Athletic Training, 2020
ContextThe increased emphasis on implementing evidence-based practice has reinforced the need to more accurately assess patient improvement. Psychometrically sound, patient-reported outcome measures are essential for evaluating patient care. A patient-reported outcome instrument that may be useful for clinicians is the Disablement in the Physically ...

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.

On the physics of the minimal length: The question of gauge invariance [PDF]

International Journal of Modern Physics A, 2016
In this note we discuss the question of gauge invariance in the presence of a minimal length. This contribution is prepared for the celebration of the 60th anniversary of the Yang–Mills theory.

Gravitational waves from first-order phase transitions in LISA: reconstruction pipeline and physics interpretation [PDF]

Journal of Cosmology and Astroparticle Physics
We develop a tool for the analysis of stochastic gravitational wave backgrounds from cosmological first-order phase transitions with LISA: we initiate a template databank for these signals, prototype their searches, and forecast their reconstruction. The

emcee v3: A Python ensemble sampling toolkit for affine-invariant MCMC [PDF]

Journal of Open Source Software, 2019
emcee is a Python library implementing a class of affine-invariant ensemble samplers for Markov chain Monte Carlo (MCMC). This package has been widely applied to probabilistic modeling problems in astrophysics where it was originally published, with some

Simultaneity as an Invariant Equivalence Relation [PDF]

, 2012
This paper deals with the concept of simultaneity in classical and relativistic physics as construed in terms of group-invariant equivalence relations.
