In B→Xsγ, there are perturbative QCD corrections at order αs not only to the single quark line process b→sγ but also coming from a set of diagrams where the weak interaction vertex involves a gluon wh...
New physics contributions to the lifetime difference in D-0-(D)over-bar(0) mixing

2014/12/20
We present the first general analysis of New Physics contributions to the D0-D̅ 0 lifetime difference (equivalently ΔΓD). We argue that New Physics (NP) contributions to |ΔC|=1 processes can domi...
Origin of optical second-harmonic generation in spherical gold nanoparticles: Local surface and nonlocal bulk contributions

Parity-violating (PV) elastic electron-proton scattering measures Q-weak for the proton, QpW
. To extract QpW from data, all radiative corrections must be well-known. Recently, disagreement on the gZ...

2010/11/19
By means of computer simulations, we investigate the relaxation of the Rouse modes in a simple bead-spring model for non-entangled polymer blends. Two different models are used for the fast component,...

Surface electric noise, i.e., the non-uniform distribution of charges and potentials on a surface, poses a great experimental challenge in modern precision force measurements. Such a challenge is enc...
Valence quark contributions for the gamma N -> P11(1440) form factors
Valence quark contributions gamma N

2010/3/16
Using a covariant spectator quark model we estimate valence quark contributions to the F1*(Q2) and F2*(Q2) transition form factors for the gamma N -> P11(1440) reaction. The Roper resonance, P11(1440)...

We study kaon photoproduction from the nucleon. Using the photon beam asymmetry, we discuss the couplings of the K and K* mesons with baryons. In previous studies of photoproductions, the...
Multiplicity distribution of final-state particles and different contributions of related sources in nucleus-nucleus collisions at high energies

2009/8/14
The final state particle multiplicity distributions in high-energy nucleus-nucleus collisions are described by two different sub-distributions contributed by a single nucleon. The Monte Carlo calculat...
