Characterization of novel lectins from Burkholderia pseudomallei and Chromobacterium violaceum with sevenbladed βpropeller fold
Burkholderia pseudomallei and Chromobacterium violaceum are bacteria of tropical and subtropical soil and water that occasionally cause fatal infections in humans and animals. Microbial lectins mediate the adhesion of organisms to host cells, which is the first phase in the development of infection. [...]

Spectrum of the reflection operators in different integrable structures
[DESY19168]
The reflection operators are the simplest examples of the nonlocal integrals of motion, which appear in many interesting problems in integrable CFT. For the so called Fateev, quantum AKNS, paperclip and KdV integrable structures, they are built from the (chiral) reflection Smatrices for the Liouville and cigar CFTs. [...]

Flattened axion monodromy beyond two derivatives
[DESY19160]
We study string inspired twofield models of largefield inflation based on axion monodromy in the presence of an interacting heavier modulus. This class of models has enough structure to approximate at least part of the backreaction effects known in full string theory, such as kinetic mixing with the axion, and flattening of the scalar potential.

Chiral FroggattNielsen models, gauge anomalies and flavourful axions
[DESY19154]
We study UVcomplete FroggattNielsenlike models for the generation of mass and mixing hierarchies, assuming that the integrated heavy fields are chiral with respect to an abelian FroggattNielsen symmetry. It modifies the mixed anomalies with respect to the Standard Model gauge group, which opens up the possibility to gauge the FroggattNielsen symmetry without the need to introduce additional spectator fermions, while keeping mass matrices usually associated to anomalous flavour symmetries.

Invisible and displaced dark matter signatures at Belle II
[DESY19141, OUTP1910P, TTK1946]
Many dark matter models generically predict invisible and displaced signatures at Belle II, but even striking events may be missed by the currently implemented search programme because of inefficient trigger algorithms. Of particular interest are final states with a single photon accompanied by missing energy and a displaced pair of electrons, muons, or hadrons. [...]

Testing the Seesaw Mechanism and Leptogenesis with Gravitational Waves
[DESY19138]
We present the possibility that the seesaw mechanism with thermal leptogenesis can be tested using the stochastic gravitational background. Achieving neutrino masses consistent with atmospheric and solar neutrino data, while avoiding nonperturbative couplings, requires right handed neutrinos lighter than the typical scale of grand unification.

Finite family groups for fermionic and leptoquark mixing patterns
[DESY19091]
We employ a bottomup and modelindependent technique to search for nonAbelian discrete flavour symmetries capable of predicting viable CKM and PMNS matrices alongside of special patterns of leptoquark couplings. In particular, we analyze patterns de rived when an ultraviolet flavour theory is assumed to break to global Abelian symmetries in Standard Model fermion masses and new Yukawalike terms sourced by the leptoquark representation.

Gluons and sea quarks in the proton at low scales

We study the evolution of parton distributions down to low scales by considering several of their Mellin moments. For the initial conditions, we use a broad array of current parton density fits. [...]

Superconformal blocks: general theory
[DESY19057]
In this work we launch a systematic theory of superconformal blocks for fourpoint functions of arbitrary supermultiplets. Our results apply to a large class of superconformal field theories including 4dimensional models with any number $ \mathcal{N} $ of supersymmetries. [...]

Monte Carlo event generators for high energy particle physics event simulation
[arXiv:1902.01674; MCnet1902]
Monte Carlo event generators (MCEGs) are the indispensable workhorses of particle physics, bridging the gap between theoretical ideas and firstprinciples calculations on the one hand, and the complex detector signatures and data of the experimental community on the other hand. All collider physics experiments are dependent on simulated events by MCEG codes such as Herwig, Pythia, Sherpa, POWHEG, and MG5_aMC@NLO to design and tune their detectors and analysis strategies.
