Die Lebenskultur der Spätantike war wesentlich durch das römische Spielewesen mit seinen Wagenrennen, Bühnenschauspielen und Arenakämpfen geprägt. Zum ersten Mal in der Forschung wird mit diesem Buch eine Gesamtstudie zum Thema spätrömischer S

Abstract Anaemia, a decrease in total concentration of haemoglobin (Hb) in blood, affects substantial percentage of the population worldwide. Currently, the gold standard for determining the Hb level is the invasive analysis of venous blood. Yet, mor

Laser wakefield acceleration (LWFA) promises compact accelerators toward the high-energy frontier. However, the approach to the 100 GeV milestone faces the obstacle of the long focal length required for optimal acceleration with high-power lasers, wh

Abstract Direct laser acceleration (DLA) of electrons in plasmas of near-critical density (NCD) is a very advancing platform for high-energy PW-class lasers of moderate relativistic intensity supporting Inertial Confinement Fusion research. Experimen

Abstract Betatron x-ray sources from laser-plasma interaction are characterized by compactness, ultrashort duration, broadband spectrum and micron source size. However, high-quality measurements with good statistics, especially in a single shot, requ

Abstract We investigate, for the first time, a scenario where the dark matter consists of three complex scalar fields that are stabilized by a single Z 7 symmetry. As an extension of the well-known scalar Higgs-portal, this Z 7 model is also subject

The phase velocity of a laser-driven wakefield can be efficiently controlled in a plasma channel. A beatwave of two long laser pulses is used. The frequency difference between these two laser pulses equals the local plasma frequency, so that the slow

Abstract The present-day B-anomalies involving b → sμ + μ − or b → cτ − ν ¯ $$ \overline{\nu} $$ transitions can all be explained with the addition of a vector U 1 leptoquark with a mass of M U 1 $$ {M}_{U_1} $$ ≳ 1.8 TeV. In the scala

Abstract The search for a Dark Matter particle is the new grail and hard-sought nirvana of the particle physics community. From the theoretical side, it is the main challenge to provide a consistent and model-independent tool for comparing the bounds

Abstract The measured branching fractions of B-mesons into leptonic final states derived by the LHCb, Belle and BaBar collaborations hint towards the breakdown of lepton flavour universality. In this work we take at face value the so-called R D ∗ $
