The short talk will be an update of the talk last year. Main topics are the ALPS II experiment, the goals and status, the experimental process, and the status of the single photon detector (TES).

New physics are highly anticipated to be observed in the near future at the LHC. Immediately ensuing a discovery is the determination of intrinsic properties such as masses and spins of new particles. However, many measurements rely on fundamental assumptions, which need not necessarily be fulfilled. One such possibility is a broad resonance at the beginning of a new physics cascade. Using the...

The physics program of the planned International Linear Collider (ILC) focuses on very high precision in measurements and searches of physics beyond the Standard Model. This places a strong demand on the ILC detectors' performance. One of the competing detector designs is the International Large Detector (ILD) which has been particularly optimised for the concept of particle flow...

Future linear colliders like ILC and CLIC could be powerful machines for the discovery and the precision study of new physics Beyond the Standard Model. Due to the intense beams (high luminosity, high energy), strong fields may occur in the beam interaction region where the physical processes take place. In the context of precision HEP, the presence of these strong fields may yield sensitive...

In this talk, I will investigate scattering amplitudes in strongly coupled N=4 Super Yang-Mills. To leading order, the amplitude at strong coupling is given in terms of a minimal surface in AdS5. The area of this surface can be calculated by a set of non-linear integral equations, which, however, do not allow an analytic solution for arbitrary kinematics.
I will demonstrate that for special...

I review the approaches to descriptions of thermal equilibrium states in both quantum mechanics and quantum field theory. I argue, that the description via (Gibbs) density functionals is not sufficient to describe thermal equilibrium states in generic situations. I show a generalization of Gibbs states, the so-called KMS-states, and their application to quantum field theory.

The fact that the renormalized energy density smeared along a timelike curve on a globally hyperbolic spacetime possesses a lower bound stimulates the pursuit of an explicit construction of a state whose energy is minimal. Such a task was completed for Robertson-Walker spacetimes and these states were named States of Low Energy. In this communication we construct such states for more general...
