Study of the weak annihilation contributions in charmless $$\varvec{B_s\rightarrow VV}$$ B s → V V decays

European Physical Journal C: Particles and Fields, 2017
In this paper, in order to probe the spectator-scattering and weak annihilation contributions in charmless $$B_s\rightarrow VV$$ B s → V V (where V stands for a light vector meson) decays, we perform the $$\chi ^2$$ χ 2 -analyses for the endpoint ...

An exact symmetry in λ-deformed CFTs

Journal of High Energy Physics, 2020
We consider λ-deformed current algebra CFTs at level k, interpolating between an exact CFT in the UV and a PCM in the IR. By employing gravitational techniques, we derive the two-loop, in the large k expansion, β-function.

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

Advanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Soft factor structure of MHV amplitudes for massless charged particles

Journal of High Energy Physics
We present a simple derivation of MHV amplitudes in massless spinor and scalar electrodynamics. Working with permutationally invariant amplitudes, we show that they are fully determined by their soft photon behavior and admit a simple factorized form in ...

Study of Nonleptonic Bq∗→DqV and PqD∗ Weak Decays

Advances in High Energy Physics, 2015
Motivated by the powerful capability of measurement for the b hadron decays at LHC and SuperKEKB/Belle-II, the nonleptonic B-∗→DD-∗, Dρ-, DK∗-, πD∗, and KD∗ decays are studied.

Simulation of Activation Experiments in an Irradiation Stand in the Context of Nuclear Decommissioning [PDF]

EPJ Web of Conferences
Monte Carlo simulations are a valuable tool to determine activated areas in nuclear power plants. This paper describes the simulation of an neutron irradiation stand containing 8 (α,n) sources and polyethylene shielding. The source spectrum of beryllium (

Tribological Performance of 60NiTi Alloy Under Varying Contact Conditions and Elevated Temperatures in Linear Reciprocating Sliding

Advanced Engineering Materials, EarlyView.
This study investigates the tribological response of 60NiTi alloy under dry, water‐lubricated and high‐temperature conditions. The alloy exhibits decreasing wear volume and friction with increasing temperature due to the formation of protective oxide layers. The work clarifies dominant wear mechanisms and demonstrates the suitability of 60NiTi for high‐

Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

Advanced Engineering Materials, EarlyView.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Hamiltonian light-front field theory within an AdS/QCD basis

, 2009
Non-perturbative Hamiltonian light-front quantum field theory presents opportunities and challenges that bridge particle physics and nuclear physics. Fundamental theories, such as Quantum Chromodynmamics (QCD) and Quantum Electrodynamics (QED) offer the ...
