Signatures of Dirac and Majorana sterile neutrinos in trilepton events at the LHC
ddc:530
Heavy sterile neutrinos with masses below MW can induce trilepton events at the 14 TeV LHC through purely leptonic $W$ decays of $W^{±}→ e^{±}e^{±}μ^{∓}ν$ and $μ^{±}μ^{±}e^{∓}ν$ where the heavy neutrino will be in an intermediate state on its mass shell. Discovery and exclusion limits for the heavy neutrinos are found using both cutandcount (CC) and multivariate analysis (MVA) methods in this study [...]

Improved determination of the Higgs mass in the MSSM with heavy superpartners
[DESY17033; arXiv:1703.08166]
ddc:530
We present several advances in the effective field theory calculation of the Higgs mass in MSSM scenarios with heavy superparticles. In particular, we compute the dominant twoloop threshold corrections to the quartic Higgs coupling for generic values of the relevant SUSYbreaking parameters, including all contributions controlled by the strong gauge coupling and by the thirdfamily Yukawa couplings.

Exact deconstruction of the 6D (2,0) theory
[DESY17030; arXiv:1704.02986]
ddc:530
The dimensionaldeconstruction prescription of ArkaniHamed, Cohen, Kaplan, Karch and Motl provides a mechanism for recovering the $A$type (2,0) theories on $T^2$, starting from a fourdimensional $\mathcal N=2$ circularquiver theory. We put this conjecture to the test using two exactcounting arguments: In the decompactification limit, we compare the Higgsbranch Hilbert series of the 4D $\mathcal N=2$ quiver to the 'halfBPS' limit of the (2,0) superconformal index. [...]

Nucleon Structure Functions from Operator Product Expansion on the Lattice
[ADP1709T1015; DESY17027; EDINBURGH201704; LIVERPOOLLTH1122; arXiv:1703.01153]
ddc:550
Deepinelastic scattering, in the laboratory and on the lattice, is most instructive for understanding how the nucleon is built from quarks and gluons. The longterm goal is to compute the associated structure functions from first principles. [...]

Gravitational waves from the asymmetricdarkmatter generating phase transition
[DESY17021; arXiv:1702.02117]
ddc:530
The baryon asymmetry, together with a dark matter asymmetry, may be produced during a first order phase transition in a generative sector. We study the possibility of a gravitational wave signal in a model realising such a scenario. [...]

Double hard scattering without double counting
[DESY17013; NIKHEF2017007; arXiv:1702.06486]
ddc:530
Double parton scattering in protonproton collisions includes kinematic regions in which two partons inside a proton originate from the perturbative splitting of a single parton. This leads to a double counting problem between single and double hard scattering. [...]

Towards the exact Bremsstrahlung function of ABJM theory
[arXiv:1705.10780]
We present the threeloop calculation of the Bremsstrahlung function associated to the 1/2BPS cusp in ABJM theory, including color subleading corrections. Using the BPS condition we reduce the computation to that of a cusp with vanishing angle. [...]

Simplified dark matter models with two Higgs doublets: I. Pseudoscalar mediators
[CERNTH2017011; DESY17010; arXiv:1701.07427]
ddc:530
We study a new class of renormalisable simplified models for dark matter searches at the LHC that are based on two Higgs doublet models with an additional pseudoscalar mediator. In contrast to the spin0 simplified models employed in analyses of Run I data these models are selfconsistent, unitary and bounds from Higgs physics typically pose no constraints. [...]

We revisit the order $\varepsilon$ dilatation operator of the WilsonFisher fixed point obtained by Kehrein, Pismak, and Wegner in light of recent results in conformal field theory. Our approach is algebraic and based only on symmetry principles. [...]

Highscale Supersymmetry, the Higgs Mass and Gauge Unification
[MCTP1706; arXiv:1706.00013]
Suppressing naturalness concerns, we discuss the compatibility requirements of highscale supersymmetry breaking with the Higgs boson mass constraint and gauge coupling unification. We find that to accommodate superpartner masses significantly greater than the electroweak scale, one must introduce large nondegeneracy factors. [...]
