Simultaneous strength and ductility enhancement of wire-arc directed energy deposited Al-Cu alloy by interlayer laser shock peening

Wire-arc directed energy deposition (wire-arc DED), recognized for its ability to produce large-scale parts, has gained considerable attention. However, a critical issue with this method is the high prevalence of internal porosity defects found in the manu ...

Update of inclusive cross sections of single and pairs of identified light charged hadrons

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Ke Huang, Donghyun Kim

We report new measurements of the production cross sections of pairs of charged pions and kaons as a function of their fractional energies using various fractional-energy definitions. Two different fractional-energy definitions were used and compared to th ...

A critical assessment of experimental investigation of dynamic recrystallization of metallic materials

Roland Logé, Ke Huang

Dynamic recrystallization (DRX) often takes place during hot deformation of metallic materials, which then exerts significant influence on the final microstructures and mechanical properties of the formed components. A considerable number of published pape ...

Azimuthal asymmetries of back-to-back pi(+/-) - (pi(0), eta, pi(+/-)) pairs in e(+) e(-) annihilation

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Ho Ling Li, Sun Hee Kim, Ke Huang, Donghyun Kim

This work reports the first observation of azimuthal asymmetries around the thrust axis in e(+)e(-) annihilation of pairs of back-to-back charged pions in one hemisphere, and pi(0) and eta mesons in the opposite hemisphere. These results are complemented b ...

Observation of tau(-) -> pi(-)nu(tau)e(+)e(-) and search for tau(-) -> pi(-)nu(tau)mu(+)mu(-)

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Ke Huang, Donghyun Kim, Lei Li

We present the first measurements of branching fractions of rare tau-lepton decays, tau(-) -> pi(-)nu(tau)l(+)l(-) (l = e or mu), using a data sample corresponding to 562 fb(-1) collected at a center-of-mass energy of 10.58 GeV with the Belle detector at t ...

Search for Omega(2012) -> K Xi(1530) -> K pi Xi at Belle

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Ke Huang, Donghyun Kim, Lei Li

Using data samples of e(+)e(-) collisions collected at the Upsilon(1S), Upsilon(2S), and Upsilon(3S) resonances with the Belle detector, we search for the three-body decay of the Omega(2012) baryon to K pi Xi. This decay is predicted to dominate for models ...

Measurement of branching fraction and final-state asymmetry for the (B)over-bar(0) -> (KSK -/+)-K-0 pi(+/-) decay

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Jun Yong Kim, Ke Huang, Ji Hyun Kim, Donghyun Kim

We report a measurement of the branching fraction and final-state asymmetry for the (B) over bar -> (KSK -/+)-K-0 pi(+/-) decays. The analysis is based on a data sample of 711 fb(-1) collected at the gamma(4S) resonance with the Belle detector at the KEKB ...

Laser shock peening: A promising tool for tailoring metallic microstructures in selective laser melting

Roland Logé, Ke Huang, Nikola Kalentics, Valerio Romano, Manuel Ortega Varela De Seijas, Andreas Burn

Metallic parts made by Selective Laser Melting (SLM) are known for their heterogeneous microstructures in the as-built (AB) state. In this paper, Laser Shock Peening (ISP) was performed on a 316 L stainless steel part fabricated by SLM. The LSP treatment i ...

Search for a Light CP-odd Higgs Boson and Low-Mass Dark Matter at the Belle Experiment

Olivier Schneider, Yiming Li, Roberto Gargiani, Chao Wang, Mithilesh Nayak, Gaétan Charles Antoine Giriat, Tagir Aushev, Sun Hee Kim, Tara Nanut, Ke Huang

We report on the first Belle search for a light CP-odd Higgs boson, A(0), that decays into low mass dark matter, chi, in final states with a single photon and missing energy. We search for events produced via the dipion transition (sic)(2S) -> (sic)(1S)pi( ...
