Nucleon anapole moment and parity-violating ep scattering
Quark nuclear Parity - violating coupling weak electricity chiral perturbation
2014/12/22
Parity-violating (PV) interactions among quarks in the nucleon induce a PV γNN coupling, or anapole moment (AM). We compute electroweak gauge-independent contributions to the AM through O(1/Λχ2) in ch...

Squarks R-parity Violating Supersymmetry ep Collisions at HERA
2011/1/4
A search for squarks in R–parity violating supersymmetry is performed in e±p collisions
at HERA using the H1 detector. The full data sample taken at a centre–of–mass
energy √s = 319 GeV is used for ...
This report is a short overview of experimental and theoretical results in J/ production in electron-proton collisions at DESY HERA with special focus lying on recent developments in inelastic photop...
Littlest Higgs model with T-parity and single top production in ep collisions
LHT model single top production production cross section
2009/8/14
Based on calculating the contributions of the littlest Higgs model with T-parity (called LHT model) to the anomalous top coupling tqγ (q=u or c), we consider single top production via the t-channel pa...
Signals of the littlest Higgs model with T-parity at eγ and ep collisions

2009/8/14
The littlest Higgs model with T-parity predicts the existence of the neutral, weakly interacting, new gauge boson BH, which can be seen as an attractive dark matter candidate. We study production of t...
