Renormalization of the threeboson system with shortrange interactions revisited
We consider renormalization of the threebody scattering problem in lowenergy effective field theory of selfinteracting scalar particles by applying timeordered perturbation theory to the manifestly Lorentzinvariant formulation. The obtained leadingorder equation is perturbatively renormalizable and nonperturbatively finite and does not require a threebody counter term in contrast to its nonrelativistic approximation..

Temperature evolution of magnetic structure of HoFeO$_3$ by single crystal neutron diffraction
We have investigated the temperature evolution of the magnetic structures of HoFeO$_3$ by single crystal neutron diffraction. The three different magnetic structures found as a function of temperature for \hfo\ are described by the magnetic groups Pb$2_1$, Pbn$2_1$ and Pbn$2_1$ and are stable in the temperature ranges $\approx$ 60055~K, 5537~K and 35$>T>2$~K respectively.

Photon asymmetry measurements of $\overrightarrow{\gamma} \mathrm{p} \rightarrow \pi^{0} \mathrm{p}$ for E$_{\gamma}$=320$$650 MeV
High statistics measurements of the photon asymmetry $\mathrm{\Sigma}$ for the $\overrightarrow{\gamma}$p$\rightarrow\pi^{0}$p reaction have been made in the center of mass energy range W=12141450 MeV. The data were measured with the MAMI A2 real photon beam and Crystal Ball/TAPS detector systems in Mainz, Germany. [...]

Measurement of the omega > pi^0 e^+e^ and eta > e^+e^g Dalitz decays with the A2 setup at MAMI
The Dalitz decays eta > e^+e^g and omega > pi^0 e^+e^ have been measured in the g p > eta p and g p > omega p reactions, respectively, with the A2 taggedphoton facility at the Mainz Microtron, MAMI. The value obtained for the slope parameter of the electromagnetic transition form factor of eta, Lambda^{2}_eta=(1.97+/0.13_tot) GeV^{2}, is in good agreement with previous measurements of the eta > e^+e^g and eta > mu^+mu^g decays.

Massive photons: an infrared regularization scheme for lattice QCD+QED
[MITCTP/4691, JLABTHY152112, NT@WM1512]
The commonly adopted approach for including electromagnetic interactions in lattice QCD simulations relies on using finite volume as the infrared regularization for QED. The longrange nature of the electromagnetic interaction, however, implies that physical quantities are susceptible to powerlaw finite volume corrections, which must be removed by performing costly simulations at multiple lattice volumes, followed by an extrapolation to the infinite volume limit.

Quantum Monte Carlo Calculations for Carbon Nanotubes
We show how lattice Quantum Monte Carlo can be applied to the electronic properties of carbon nanotubes in the presence of strong electronelectron correlations. We employ the pathintegral formalism and use methods developed within the lattice QCD community for our numerical work. [...]
