A Lorentzian inversion formula for defect CFT
[DESY19039; arXiv:1903.05222]
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
[DESY19078; DOTH 19/06; arXiv:1905.03728]
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; DESY19076; IMSC/2019/05/04]
We present an accurate theoretical prediction for the production of Higgs boson through bottom quark annihilation at the LHC up to nexttonexttonextto leading order (N$^3$LO) plus nexttonexttonexttoleading 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; CMSHIG18005; CERNEP2018343]
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 protonproton collision data

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. [...]

[arXiv:1903.04560; CMSHIG18014; CERNEP2019025]
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 protonproton collision data recorded by the CMS experiment in 2016 at a centerofmass energy of 13 TeV, corresponding to an integrated luminosity of 35.9\fbinv. [...]
