A Lorentzian inversion formula for defect CFT
[DESY-19-039; arXiv:1903.05222]
 GO
We present a Lorentzian inversion formula valid for any defect CFT that extracts the bulk channel CFT data as an analytic function of the spin variable. This result complements the already obtained inversion formula for the corresponding defect channel, and makes it now possible to implement the analytic bootstrap program for defect CFT, by going back and forth between both channels.

Three loop QCD corrections to heavy quark form factors
[DESY-19-078; DO-TH 19/06; arXiv:1905.03728]
 GO
Higher order calculations in perturbative Quantum Field Theories often produce coupled linear systems of differential equations which factorize to first order. Here we present an algorithm to solve such systems in terms of iterated integrals over an alphabet the structure of which is implied by the coefficient matrix of the given system. [...]

Resummed prediction for Higgs boson production through $b\bar{b}$ annihilation at N$^3$LO+N$^3$LL
[arXiv:1905.03771; DESY-19-076; IMSC/2019/05/04]
 GO
We present an accurate theoretical prediction for the production of Higgs boson through bottom quark annihilation at the LHC up to next-to-next-to-next-to leading order (N$^3$LO) plus next-to-next-to-next-to-leading logarithmic (N$^3$LL) accuracy. We determine the third order perturbative Quantum Chromodymanics (QCD) correction to the process dependent constant in the resummed expression using the three loop bottom quark form factor and third order quark soft distribution function.

Search for a heavy pseudoscalar boson decaying to a Z and a Higgs boson at $\sqrt{s}=$ 13 TeV
[arXiv:1903.00941; CMS-HIG-18-005; CERN-EP-2018-343]
 GO
A search is presented for a heavy pseudoscalar boson A decaying to a Z boson and the standard model Higgs boson. In the final state considered, the Higgs boson decays to a bottom quark and antiquark, and the Z boson decays either into a pair of electrons, muons, or neutrinos. [...]

An embedding technique to determine $\tau\tau$ backgrounds in proton-proton collision data
[arXiv:1903.01216; CMS-TAU-18-001; CERN-EP-2019-012]
 GO
An embedding technique is presented to estimate standard model $\tau\tau$ backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed $\mu\mu$ events and replaced with simulated tau leptons with the same kinematic properties. [...]

 GO
A measurement is presented of electroweak (EW) production of a W boson in association with two jets in proton-proton collisions at $\sqrt{s}=$ 13 TeV. The data sample was recorded by the CMS Collaboration at the LHC and corresponds to an integrated luminosity of 35.9 fb$^{-1}$. [...]

Search for charged Higgs bosons in the H$^{\pm} \to \tau^{\pm}\nu_\tau$ decay channel in proton-proton collisions at $\sqrt{s}=$ 13 TeV
[arXiv:1903.04560; CMS-HIG-18-014; CERN-EP-2019-025]
 GO
A search is presented for charged Higgs bosons in the H$^{\pm} \to \tau^{\pm}\nu_\tau$ decay mode in the hadronic final state and in final states with an electron or muon. The search is based on proton-proton collision data recorded by the CMS experiment in 2016 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9\fbinv. [...]
