The anomalous chiral Lagrangian at order p 8

Journal of High Energy Physics
We derive the order p 8 Lagrangian of odd intrinsic parity for mesonic chiral perturbation theory, and provide the resulting operator basis in the supplementary material.

The ϒ(1S)→Bcρ decay with perturbative QCD approach

Nuclear Physics B, 2016
With the potential prospects of the ϒ(1S) data samples at the running LHC and upcoming SuperKEKB, the ϒ(1S)→Bcρ weak decay is studied with the pQCD approach.

First‐Principles Modeling of Solid Solution Softening and Hardening Effects in Al–Mg–Zr–Si Aluminum Alloys

Advanced Engineering Materials, EarlyView.
The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...

Bc→BP,BV Decays with the QCD Factorization Approach

Advances 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

A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

Advanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

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

European 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 ...

Advancing Wildfire‐Retardant Materials: Engineering Strategies for Direct and Indirect Suppression

Advanced Engineering Materials, EarlyView.
Here, the evolution, ecological impact, and performance of current fire‐retardant materials and suppression strategies are reviewed, offering an engineering perspective to address existing challenges and propose pathways for the development of more effective, scalable, and sustainable solutions to meet the demands of a changing climate. Wildfires cause

Cuts of Feynman Integrals in Baikov representation

Journal of High Energy Physics, 2017
Based on the Baikov representation, we present a systematic approach to compute cuts of Feynman Integrals, appropriately defined in d dimensions. The information provided by these computations may be used to determine the class of functions needed to ...

Scattering amplitudes and soft theorems in multi-flavor Galileon theories

Journal of High Energy Physics, 2020
In this paper we initiate the study of multi-flavor Galileon theories using the methods of scattering amplitudes. We explore this topic from different perspectives and extend the techniques employed so far mainly in the single-flavor case.

Experimental Techniques in Nuclear and Particle Physics [PDF]

, 2009
I have been teaching courses on experimental techniques in nuclear and particle physics to master students in physics and in engineering for many years. This book grew out of the lecture notes I made for these students. The physics and engineering students have rather different expectations of what such a course should be like.
