Quantum Groups and Asymptotic Symmetries
Josua Unger
This thesis is devoted to the study of Lie bialgebra and Hopf algebra structures related to certain versions of non-commutative geometry constructed on infinite-dimensional Lie alg…
-deformed complex fields and discrete symmetries
Michele Arzano, Andrea Bevilacqua, Jerzy Kowalski-Glikman +2
We present a construction of -deformed complex scalar field theory with the objective of shedding light on the way discrete symmetries and CPT invariance are affected by the def…
BMS algebras in 4 and 3 dimensions, their quantum deformations and duals
A. Borowiec, L. Brocki, J. Kowalski-Glikman +1
BMS symmetry is a symmetry of asymptotically flat spacetimes in the vicinity of the null boundary of spacetime and it is expected to play a fundamental role in physics. It is inter…
Quantum ergosphere and brick wall entropy
Michele Arzano, Lennart Brocki, Jerzy Kowalski-Glikman +2
We revisit the "brick wall" model for black hole entropy taking into account back-reaction effects on the horizon structure. We do so by adopting an evaporating metric in the quasi…
-deformed BMS symmetry
A. Borowiec, L. Brocki, J. Kowalski-Glikman +1
We present the quantum -deformation of BMS symmetry, by generalizing the lightlike -Poincaré Hopf algebra. On the technical level, our analysis relies on the fact that the li…
Three-loop MSSM Higgs-Boson Mass Predictions and Regularization by Dimensional Reduction
Dominik Stöckinger, Josua Unger
The evaluation of three-loop contributions to the MSSM Higgs-boson mass is considered at the orders enhanced by the strong gauge coupling and top or bottom Yukawa couplings, i.e. a…
