Physics in curved spacetime describes a multitude of phenomena, ranging from astrophysics to high energy physics. The last few years have witnessed further progress on several fronts, including the accurate numerical evolution of the gravitational field equations, which now allows highly nonlinear phenomena to be tamed. Numerical relativity simulations, originally developed to understand strong field astrophysical processes, could prove extremely useful to understand high-energy physics processes like trans-Planckian scattering and gauge-gravity dualities. We present a concise and comprehensive overview of the state-of-the-art and important open problems in the field(s), along with guidelines for the next years. This writeup is a summary of the NR/HEP Workshop held in Madeira, Portugal from August 31st to September 3rd 2011.

Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requ
ires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade.
The Young Physicists Panel (YPP) summarizes results from their Survey on the Future of High Energy Physics, which was conducted from July 2 to July 15, 2001. Over 1500 physicists from around the world, both young and tenured, responded to the survey.
We first describe the origin, design, and advertisement of the survey, and then present the demographics of the respondents. Following sections analyze the collected opinions on the desire for balance in the field, the impact of globalization, the necessity of outreach, how to build the field, the physics that drives the field, and the selection of the next big machine. Respondents comments follow the survey analysis in an appendix.
Cataclysmic astrophysical phenomena can produce impulsive gravitational waves that can possibly be detected by the advanc
We analyze properties of unstable vacuum states from the point of view of the quantum theory. In the literature one can find some suggestions that some of false (unstable) vacuum states may survive up to times when their survival probability has a no
n-exponential form. At asymptotically late times the survival probability as a function of time $t$ has an inverse power--like form. We show that at this time region the energy of the false vacuum states tends to the energy of the true vacuum state as $1/t^{2}$ for $t to infty$. This means that the energy density in the unstable vacuum state should have analogous properties and hence the cosmological constant $Lambda = Lambda (t)$ too. The conclusion is that $Lambda$ in the Universe with the unstable vacuum should have a form of the sum of the bare cosmological constant and of the term of a type $1/t^{2}$: $Lambda(t) equiv Lambda_{bare} + d/ t^{2}$ (where $Lambda_{bare}$ is the cosmological constant for the Universe with the true vacuum).
Within the approach to doubly special relativity (DSR) suggested by Magueijo and Smolin, a new algebraically justified rule of so-called $kappa$-addition for the energies of identical particles is proposed. This rule permits to introduce the nonlinea
r $kappa$-dependent Hamiltonian for one-mode multi-photon (sub)system. On its base, with different modes treated as independent, the thermodynamics of black-body radiation is explored within DSR, and main thermodynamic quantities are obtained. In their derivation, we use both the analytical tools within mean field approximation (MFA) and numerical evaluations based on exact formulas. The entropy of one-mode subsystem turns out to be finite (bounded). Another unusual result is the existence of threshold temperature above which radiation is present. Specific features of the obtained results are explained and illustrated with a number of plots. Comparison with some works of relevance is given.
