The Cherenkov Telescope Array, CTA, will be the major global observatory for very high energy gamma-ray astronomy over next decade and beyond. scientific potential of CTA is extremely broad: from understanding role relativistic cosmic particles to search dark matter. an explorer extreme universe, probing environments immediate neighbourhood black holes voids on largest scales. Covering a huge range in photon 20 GeV 300 TeV, improve all aspects performance with respect current instruments....
One of the simplest viable models for dark matter is an additional neutral scalar, stabilised by a Z2 symmetry. Using GAMBIT package and combining results from four independent samplers, we present Bayesian frequentist global fits this model. We vary singlet mass coupling along with 13 nuisance parameters, including nuclear uncertainties relevant direct detection, local density, selected quark masses couplings. include relic density measured Planck, searches LUX, PandaX, SuperCDMS XENON100,...

The Compact Linear Collider (CLIC) is a multi-TeV high-luminosity linear e+e- collider under development. For an optimal exploitation of its physics potential, CLIC foreseen to be built and operated in staged approach with three centre-of-mass energy stages ranging from few hundred GeV up 3 TeV. first stage will focus on precision Standard Model physics, particular Higgs top-quark measurements. Subsequent measurements rare processes, as well searches for new processes states, e.g. states...
We provide an updated assessment of the power Cherenkov Telescope Array (CTA) to search for thermally produced dark matter at TeV scale, via associated gamma-ray signal from pair-annihilating particles in region around Galactic centre. find that CTA will open a new window discovery potential, significantly extending range robustly testable models given standard cuspy profile density distribution. Importantly, even cored profile, projected sensitivity be sufficient probe various...
Abstract Sub-GeV dark matter (DM) particles produced via thermal freeze-out evade many of the strong constraints on heavier DM candidates but at same time face a multitude new from laboratory experiments, astrophysical observations and cosmological data. In this work we combine all these in order to perform frequentist Bayesian global analyses fermionic scalar sub-GeV coupled photon with kinetic mixing. For DM, find viable parameter regions close resonance, which expand significantly when...
With a large integrated luminosity expected at the Tevatron, next-to-leading order (NLO) calculation is no longer sufficient to describe data which yield precision measurement of $M_W$, etc. Thus, we extend Collins-Soper-Sterman resummation formalism, for on-shell vector boson production, correctly include effects polarization and width distributions decay leptons. We show how test rich dynamics QCD multiple soft gluon radiation, example, by measuring ratio $R_{CSS} \equiv \frac{\sigma...

We present global analyses of effective Higgs portal dark matter models in the frequentist and Bayesian statistical frameworks.

We investigate rarely explored details of supercooled cosmological first-order phase transitions at the electroweak scale, which may lead to strong gravitational wave signals or explain cosmic baryon asymmetry. The nucleation temperature is often used in transition analyses, and defined through condition: on average one bubble has nucleated per Hubble volume. argue that neither a fundamental nor essential quantity analysis. illustrate scenarios where can complete without satisfying...
Abstract An epoch of matter domination in the early universe can enhance primordial stochastic gravitational wave signal, potentially making it detectable to upcoming experiments. However, resulting signal is quite sensitive end matter-dominated epoch. If ends gradually, a cancellation results an extremely suppressed while limit instantaneous transition, there resonant-like enhancement. The dominated cannot be instantaneous, however, and previous analyses have used Gaussian smoothing...
