The Dependence on the Number of Quark Flavours in Lattice QED [PDF]

open access: yes, 2000
The dependence on the number of flavours in lattice QED with our new fermion action is investigated by Monte Carlo simulations. This action possesses the discrete chiral symmetry and provides 2D-component fermions,which should be compared with 2 1+D ...

Dimuon and ditau production in photon-photon collisions at next-to-leading order in QED [PDF]

open access: yesJournal of High Energy Physics
Next-to-leading-order (NLO) quantum electrodynamics (QED) corrections to the production of muon and tau pairs in photon-photon collisions, γγ → μ+μ−, τ+τ−, are calculated in the equivalent photon approximation.

Artificial Intelligence‐Driven Natural Product Drug Discovery: From Computational Genome Mining to Clinical Translation

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Natural products (NPs) have historically yielded numerous therapeutic agents, yet their integration into modern drug discovery has been constrained by chemical complexity, low abundance, laborious dereplication, and limited target annotation.

Neutrino trident scattering at near detectors

open access: yesJournal of High Energy Physics, 2019
Neutrino trident scattering is a rare Standard Model process where a charged-lepton pair is produced in neutrino-nucleus scattering. To date, only the dimuon final-state has been observed, with around 100 total events, while the other channels are as yet

High‐purity X‐ray polarimetry at high energies for Mössbauer spectroscopy

open access: yesJournal of Synchrotron Radiation, EarlyView.
This work extends high‐purity X‐ray polarimetry into the 15–30 keV range, enabling polarization‐filtered synchrotron Mössbauer spectroscopy of higher‐energy nuclear resonances. A proof‐of‐principle experiment at 22.494 keV demonstrates a polarization purity of (1.2 ± 0.5) × 10−8, establishing the feasibility of the approach.High‐purity X‐ray ...

Measurement of V0 production ratios in pp collisions at √s=0.9 and 7 TeV [PDF]

open access: yes, 2011
The Λ/Λ and Λ/K0S production ratios are measured by the LHCb detector from 0.3 nb−1 of pp collisions delivered by the LHC at √s = 0.9 TeV and 1.8 nb−1 at √s = 7 TeV.

Parity violation in Møller scattering within low-energy effective field theory

open access: yesJournal of High Energy Physics
We include electroweak effects in Møller scattering at low energies in an effective field theory approach and compute the left-right parity-violating asymmetry.

An explanation for the muon and electron g − 2 anomalies and dark matter

open access: yesJournal of High Energy Physics, 2020
We propose simple models with a flavor-dependent global U(1)ℓ and a discrete ℤ2 symmetries to explain the anomalies in the measured anomalous magnetic dipole moments of muon and electron, (g − 2) μ,e , while simultaneously accommodating a dark matter ...

Discrete symmetries tested at 10−4 precision using linear polarization of photons from positronium annihilations [PDF]

open access: yesNature Communications
Discrete symmetries play an important role in particle physics with violation of CP connected to the matter-antimatter imbalance in the Universe. We report the most precise test of P, T and CP invariance in decays of ortho-positronium, performed with ...
