Lattice QCD study of the $H$ dibaryon using hexaquark and two-baryon interpolators
[CERN-TH-2018-098; DESY 18-066; HIM-2018-02; MITP/18-030; TIFR/TH/18-12; CERN-TH-2018-098; DESY-18-066; HIM-2018-02; MITP-18-030; --TIFR-TH-18-12; arXiv:1805.03966; --TIFR-TH-18-12]
We present a lattice QCD spectroscopy study in the isospin singlet, strangeness $-2$ sectors relevant for the conjectured $H$ dibaryon. We employ both hexaquark and two-baryon interpolating operators to isolate the ground state in the rest frame and in moving frames. [...]

Line defects and radiation in $\mathcal{N}=2$ theories
[DESY-18-071; arXiv:1805.04111]
 GO
We study the conformal data of a generic superconformal half-BPS line defect in a four-dimensional $\mathcal{N} = 2$ theory. We prove a theory independent relation between the one-point function of the stress tensor in the presence of the line defect and the two-point function of the displacement operator. [...]

The Muon g-2 in Progress
[DESY-18-057; HU-EP-18-11; arXiv:1804.07409]
Two next generation muon $g-2$ experiments at Fermilab in the US and at J-PARC in Japan have been designed to reach a four times better precision from 0.54 ppm to 0.14 ppm and the challenge for the theory side is to keep up in precision as far as possible. This has triggered a lot of new research activities. [...]

Search for ZZ resonances in the 2$\ell$2$\nu$ final state in proton-proton collisions at 13 TeV
[CMS-B2G-16-023; CERN-EP-2017-279; arXiv:1711.04370]
A search for heavy resonances decaying to a pair of Z bosons is performed using data collected with the CMS detector at the LHC. Events are selected by requiring two oppositely charged leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum, which is interpreted as arising from the decay of a second Z boson to two neutrinos. [...]

Measurement of differential cross sections for the production of top quark pairs and of additional jets in lepton+jets events from pp collisions at $\sqrt{s} =$ 13 TeV
[CMS-TOP-17-002; CERN-EP-2018-039; arXiv:1803.08856]
 GO
Differential and double-differential cross sections for the production of top quark pairs in proton-proton collisions at $\sqrt{s} =$ 13 TeV are measured as a function of kinematic variables of the top quarks and the top quark-antiquark ($\mathrm{t}\overline{\mathrm{t}}$) system. In addition, kinematic variables and multiplicities of jets associated with the $\mathrm{t}\overline{\mathrm{t}}$ production are measured. [...]

Heavy Quark Form Factors at Three Loops in the Planar Limit
[DESY-18-052; DO-TH-18-08]
 GO
We compute the color-planar and complete light quark non-singlet contributions to the heavy quark form factors in the case of the axialvector, scalar and pseudoscalar currents at three loops in perturbative QCD. We evaluate the master integrals applying a new method based on differential equations for general bases, which is applicable for all first order factorizing systems. [...]

Search for a new heavy resonance decaying into a Z boson and a Z or W boson in 2$\ell$2q final states at $\sqrt{s}=$ 13 TeV
[CMS-B2G-17-013; CERN-EP-2018-037; arXiv:1803.10093]
 GO
A search has been performed for new, heavy resonances decaying to ZZ or ZW in 2$\ell$2q final states, with two charged leptons ($\ell=$ e,$\mu$) produced by the decay of a Z boson, and two quarks produced by the decay of a W or Z boson. The analysis is sensitive to resonances with masses in the range from 400 to 4500 GeV. [...]

Search for a heavy right-handed W boson and a heavy neutrino in events with two same-flavor leptons and two jets at $\sqrt{s}=$ 13 TeV
[CMS-EXO-17-011; CERN-EP-2018-028; arXiv:1803.11116]
 GO
A search for a heavy right-handed W boson (W$_\mathrm{R}$) decaying to a heavy right-handed neutrino and a charged lepton in events with two same-flavor leptons (e or $\mu$) and two jets, is presented. The analysis is based on proton-proton collision data, collected by the CMS Collaboration at the LHC in 2016 and corresponding to an integrated luminosity of 35.9 fb$^{-1}$. [...]

 GO
A search for new high-mass resonances in proton-proton collisions having final states with an electron or muon and missing transverse momentum is presented. The analysis uses proton-proton collision data collected in 2016 with the CMS detector at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$.

Search for a new scalar resonance decaying to a pair of Z bosons in proton-proton collisions at $\sqrt{s} =$ 13 TeV
[CMS-HIG-17-012; CERN-EP-2018-009; arXiv:1804.01939]
 GO
A search for a new scalar resonance decaying to a pair of Z bosons is performed in the mass range from 130 GeV to 3 TeV, and for various width scenarios. The analysis is based on proton-proton collisions recorded by the CMS experiment at the LHC in 2016, corresponding to an integrated luminosity of 35.9 fb$^{-1}$ at a center-of-mass energy of 13 TeV.
