Hard-Thermal-Loop QCD thermodynamics and quark number susceptibility

EPJ Web of Conferences, 2014
The weak-coupling expansion of the QCD pressure is known up to the order g6 log g. However, at experimentally relevant temperatures, the corresponding series is poorly convergent.

Leptonic flavor structure in the brane shifted extra dimensional seesaw mechanism

European Physical Journal C: Particles and Fields, 2018
We discuss the leptonic flavor structure generated by a brane shifted extra dimensional seesaw model with a single right handed neutrino in the bulk. In contrast to previous works, no unitarity approximation for the $$3 \times 3$$ 3×3 submatrix has been ...

A concept to generate ultrashort ion pulses for pump-probe experiments in the keV energy range

New Journal of Physics, 2019
The impact of an energetic particle onto a solid surface generates a strongly perturbed and extremely localized non-equilibrium state, which relaxes on extremely fast time scales.

Dynamic critical behavior of the chiral phase transition from the real-time functional renormalization group

Journal of High Energy Physics
The collective dynamics around the second-order O(4) chiral phase transition in QCD with two massless quark flavors can be understood by appealing to universality.

Nucleon-nucleon scattering in the 1S0 partial wave in the modified Weinberg approach

EPJ Web of Conferences, 2016
Nucleon-nucleon scattering in the 1S0 partial wave is considered in chiral effective field theory within the recently suggested renormalizable formulation based on the Kadyshevsky equation.

High-energy neutrinos from blazars [PDF]

EPJ Web of Conferences
Identifying the origin of the majority of high-energy cosmic neutrinos observed by the IceCube Neutrino Observatory remains a significant challenge. Previous studies reported evidence of a spatial correlation between blazars listed in the 5th Roma-BZCat ...

Sterile neutrino shortcuts in asymmetrically warped extra dimensions

European Physical Journal C: Particles and Fields, 2019
Light sterile neutrinos are a popular extension of the Standard Model and are being discussed as a possible explanation for various neutrino oscillation anomalies, including the LSND, MiniBooNE, Reactor and Gallium anomalies.

Appearance of flat surface bands in three-dimensional topological insulators in a ferromagnetic exchange field

New Journal of Physics, 2014
We study the properties of the surface states in three-dimensional topological insulators in the presence of a ferromagnetic exchange field. We demonstrate that for layered materials like $\text{Bi}_2 \text{Se}_3$ the surface states on the top surface ...

Numerical Evaluation of a Soliton Pair with Long-Range Interaction

Universe
We determine the interaction energy of electric monopole pairs, sources and sinks of a Coulombic field. These charges are represented by topological solitons of finite size and mass, described by a field of SO(3) rotations without any divergences.
