Computing the magnetic field response of the proton [PDF]

EPJ Web of Conferences, 2020
Background field methods offer an approach through which fundamental non-perturbative hadronic properties can be studied. Lattice QCD is the only ab initio method with which Quantum Chromodynamics can be studied at low energies; it involves numerically ...

Pion, muon decays and weak interaction symmetries

, 2010
We review the recent measurements of the rare pion decays: Pi+ -> Pi0 e+ Nu [pion beta, Pi_(e3), or Pi_beta decay], radiative decay Pi+ -> e+ Nu Gamma [Pi_(e2Gamma) or RPD], and Pi+ -> e+ Nu [Pi_(e2)] decay, as well as the radiative muon decay, Mu -> e ...

Improving the Tracking of Subatomic Particles Using the Unscented Kalman Filter With Measurement Redundancy in High Energy Physics Experiments

IEEE Access, 2019
In this paper, the unscented Kalman filter (UKF) is applied to a particle tracking problem in the high energy physics (HEP) experiments, where the determination of position and momentum associated to a particle with a high level of the desired accuracy ...

Non-resonant leptogenesis in seesaw models with an almost conserved B-L

, 2013
We review the motivations and some results on leptogenesis in seesaw models with an almost conserved lepton number. The paper is based on a talk given at the 5th International Symposium on Symmetries in Subatomic Physics, SSP2012.Comment: 8 pages, 1 ...

Enhanced structural stability and optoelectronic properties of lead-free α-phase CsSnI3 perovskite via Zn and Cu doping

Results in Engineering
Lead-free tin halide perovskites, such as cubic-phase α-CsSnI3, face structural instability challenges in photovoltaic applications. Using density functional theory (DFT) with a 2×2×1 supercell, we investigate the effects of Zn and Cu doping on ...

The quark-meson coupling model and chiral symmetry

, 2010
We extend the quark-meson coupling (QMC) model to incorporate chiral symmetry. The relationship between the QMC model and chiral perturbation theory is also discussed.

Confinement, Vacuum Structure: from QCD to Quantum Gravity

, 2010
A minimal Lorentz gauge gravity model with R^2-type Lagrangian is proposed. In the absence of torsion the model admits a topological phase with unfixed metric. The model possesses a minimal set of dynamical degrees of freedom for the torsion. Remarkably,

Commissioning of the J-PET detector for studies of decays of positronium atoms [PDF]

, 2017
The Jagiellonian Positron Emission Tomograph (J-PET) is a detector for medical imaging of the whole human body as well as for physics studies involving detection of electron-positron annihilation into photons.

CP Violation in $\Lambda$ to p $\pi^-$: SM vs New Physics

, 2000
I discuss CP violation in $\Lambda$ to p $\pi^-$ comparing the standard model expectations with what could happen in new physics scenarios. I point out that Fermilab experiment E871 is sensitive to some of these scenarios.Comment: 6 pages, Talk at ...

One Metasurface for Four‐Channel Terahertz Wavefront Manipulation Based on Vanadium Dioxide

Advanced Physics Research, EarlyView.
This article presents a thermally reconfigurable metasurface utilizing vanadium dioxide (VO2) to dynamically switch between four independent wavefront‐manipulation channels. By synergizing geometric and propagation phases, the platform enables spin‐decoding for circularly polarized waves and polarization multiplexing for linearly polarized waves ...
