Revisiting the form factors of $$P\rightarrow V$$ P→V transition within the light-front quark models

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We investigate the self-consistency and Lorentz covariance of the covariant light-front quark model (CLF QM) via the matrix elements and form factors ($${{\mathcal {F}}}=g$$ F=g , $$a_{\pm }$$ a± and f) of $$P\rightarrow V$$ P→V transition.

On the stability of AdS backgrounds with λ-deformed factors

open access: yesJournal of High Energy Physics, 2021
We investigate the stability of the non-supersymmetric solutions of type-IIB supergravity having an unwarped AdS factor and λ-deformed subspaces found in [26]. Among the plethora of solutions we study the perturbative stability of backgrounds with an AdS

Spin-Isospin Excitations and Muon Capture by Nuclei

open access: yes, 2005
By analyzing the energy-weighted moments of the strength function calculated in RPA and beyond it is shown that the explanation of the effect of missing strength of Gamow-Teller transitions requires that residual interaction produce high-excited $1 ...

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

open access: yesAdvanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Study on the Υ(1S)→BcM Weak Decays

open access: yesAdvances in High Energy Physics, 2015
Motivated by the prospects of the potential Υ(1S) particle at high-luminosity heavy-flavor experiments, we studied the Υ(1S)→BcM weak decays, where M = π, ρ, K(∗). The nonfactorizable contributions to hadronic matrix elements are taken into consideration

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Revisiting $$B_s \rightarrow PP$$ B s → P P and PV decays with contributions from $${\phi }_{B2}$$ ϕ B 2 with the perturbative QCD approach

open access: yesEuropean Physical Journal C: Particles and Fields
The $$B_s \rightarrow PP$$ B s → P P and PV decay modes are revisited at leading order within the perturbative QCD (pQCD) approach, incorporating the $$B_s$$ B s mesonic wave function (WF) $${\phi }_{B2}$$ ϕ B 2 .

Understanding Supernova Neutrino Physics using Low-Energy Beta-Beams

open access: yes, 2005
We show that fitting linear combinations of low-energy beta-beam spectra to supernova-neutrino energy-distributions reconstructs the response of a nuclear target to a supernova flux in a very accurate way. This allows one to make direct predictions about

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

The nonfactorizable QED correction to the $$\overline{B}_{s}$$ B ¯ s $${\rightarrow }$$ → $$D_{s}^{(*)} {\ell } \bar{\nu }_{\ell }$$ D s ( ∗ ) ℓ ν ¯ ℓ decays

open access: yesEuropean Physical Journal C: Particles and Fields
Considering the nonfactorizable QED corrections, the branching ratios and ratios of branching ratios $$R(D_{s}^{({*})})$$ R ( D s ( ∗ ) ) for the semileptonic $$\overline{B}_{s}$$ B ¯ s $${\rightarrow }$$ → $$D_{s}^{(*)} {\ell } \bar{\nu }_{\ell }$$ D s (
