Sensitivity of the ILC to light Higgs masses
[DESY-17-193; arXiv:1801.09662]
The particle discovered in the Higgs boson searches at the LHC with a mass of about 125 GeV can be identified with one neutral Higgs boson in a variety of Beyond the Standard Model (BSM) theories with an extended Higgs sector. Limits on the couplings between additional Higgs fields to the electroweak gauge-bosons in such theories can be obtained by model-independent Higgs searches at lepton colliders. [...]

The fate of the Littlest Higgs Model with T-parity under 13 TeV LHC Data
[DESY-17-192; arXiv:1801.06499]
We exploit all LHC available Run 2 data at center-of-mass energies of 8 and 13 TeV for searches for physics beyond the Standard Model. We scrutinize the allowed parameter space of Little Higgs models with the concrete symmetry of T-parity by providing comprehensive analyses of all relevant production channels of heavy vectors, top partners, heavy quarks and heavy leptons and all phenomenologically relevant decay channels. [...]

Top-philic dark matter within and beyond the WIMP paradigm
[DESY-18-018; TUM-HEP 1131/18; TTK-18-05; arXiv:1802.00814]
We present a comprehensive analysis of top-philic Majorana dark matter that interacts via a colored t-channel mediator. Despite the simplicity of the model -- introducing three parameters only -- it provides an extremely rich phenomenology allowing to accommodate the relic density for a large range of coupling strengths spanning over six orders of magnitude. [...]

The light bound states of $\mathcal{N}=1$ supersymmetric SU(3) Yang-Mills theory on the latticeThep
[DESY-18-008; MS-TP-18-04; arXiv:1801.08062]
In this article we summarise our results from numerical simulations of $\mathcal{N}=1$ supersymmetric Yang-Mills theory with gauge group SU(3). We use the formulation of Curci and Veneziano with clover-improved Wilson fermions. [...]

Exclusive top production at a Linear Collider at and off the threshold
[DESY-18-013; LTH 1151; MITP/18-007; SI-HEP-2018-07; UWThPh2018-2; arXiv:1801.08083]
We review exclusive top pair production including decays at a future high-energy lepton collider, both in the threshold region and for higher energies. For the continuum process, we take complete QCD next-to-leading order matrix elements for the $2\to 6$ process with leptonic W decays into account. [...]

N-jettiness subtractions for g g → H at subleading power
[DESY-17-128] ddc:530
N-jettiness subtractions provide a general approach for performing fully-differential next-to-next-to-leading order (NNLO) calculations. Since they are based on the physical resolution variable N-jettiness, $\mathcal{T}$N, subleading power corrections in $\tau=\mathcal{T}$N/Q, with Q a hard interaction scale, can also be systematically computed [...]

Nonperturbative and Numerical Approaches to Quantum Gravity, String Theory and Holography, Meeting locationBangalore, India, 27 Jan 2018 - 3 Feb 20182018-01-272018-02-03
In this introductory lecture we review basic CFT tools, which include representation theory of the conformal algebra and the operator product expansion. We prove that two- and three-point functions are completely fixed by conformal symmetry, while four-point functions depend on two conformal invariants. [...]
