Matrix element corrections in top quark decays for the $$t\overline{t}W^{\pm }$$ t t ¯ W ± process

open access: yesEuropean Physical Journal C: Particles and Fields
We present a method that allows enabling matrix element corrections (MECs) in Pythia8 with MC@NLO matching, without incurring double counting. MECs are an interesting feature that may contribute to the accuracy of theoretical predictions, alongside ...

Reduced Lagrangians and analytic solutions in Einstein-æther cosmology

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We present the solution space of the field equations in the Einstein-æther theory for the case of a FLRW and a locally rotationally symmetric (LRS) Bianchi type III space-time.

The Life and Legacy of Pomeranchuk

open access: yes, 2003
The life of Isaak Yakovlevich Pomeranchuk was short (20.05.1913 -- 14.12.1966). But the impact of his personality and his works on physics and physicists is remarkable. The talk describes the biography of I.Ya.

Efficient Multifunctional Response and Polarization Switching in BiFeO3–PbZr0.58Ti0.42O3–MnFe2O4‐Based Triphasic Composites for Advanced Pulsating Applications

open access: yesAdvanced Engineering Materials, EarlyView.
Triphasic BiFeO3–PbZr0.58Ti0.42O3–MnFe2O4 composites exhibit enhanced ferroelectric and magnetic behavior, achieving 70.76% energy‐storage efficiency and improved polarization switching. The coupling between ferroelectric and magnetic phases enables multifunctional performance, making these composites promising candidates for next‐generation energy ...

Bc→BP,BV Decays with the QCD Factorization Approach

open access: yesAdvances in High Energy Physics, 2015
We studied the nonleptonic Bc→BP, BV decays with the QCD factorization approach. It is found that the Cabibbo favored processes of Bc→Bsπ, Bsρ, BuK- are the promising decay channels with branching ratio larger than 1%, which should be observed earlier by

Beta-beams

open access: yes, 2008
Beta-beams is a new concept for the production of intense and pure neutrino beams. It is at the basis of a proposed neutrino facility, whose main goal is to explore the possible existence of CP violation in the lepton sector.

Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.
