abstract = {In this thesis, we present the novel Monte Carlo Event
Generator $\mathtt{history}$ which is designed to predict
fully-differential cross sections for color-singlet final
states at next-to-next-to-leading order accuracy in
perturbative quantum chromodynamics. This precision level is
achieved through the application of the Nested
Soft-Collinear Subtraction scheme, a fully local method to
subtract infrared divergences that arise during phase-space
integrations. We review the concepts behind this scheme and
present the essential components which are crucial for a
practical implementation. This includes a collection of the
explicit expressions for all subtraction functions that are
substantial for arbitrary color-singlet-production processes
initiated by a quark-antiquark pair at leading order.
Furthermore, we outline the adopted phase-space
parametrization, that originally has been introduced in the
$\mathtt{STRIPPER}$ framework. In conclusion, we obtain a
flexible program that enables fast and numerically stable
evaluations of higher-order corrections. The code of
$\mathtt{history}$ contains a process-independent
implementation of the subtraction scheme that has to be
combined with process-specific matrix elements. The current
version provides a phenomenological application to Higgs
boson production in association with a weak gauge boson in
hadron collisions. Thereby, the focus lies on the
Drell-Yan-like production mechanism, $pp \to V^\ast \to
V\!H$, where $V$ represents either a $W$ or a $Z$ boson, but
also the loop-induced gluon-fusion process, which
exclusively contributes to $Z\!H$ production, is included at
$\mathcal{O}(\alpha_s^2)$. Cross-section predictions can be
made within the Standard Model and in theories beyond the
Standard Model. Particularly, the Two-Higgs-Doublet Model
and the B-L Model are accessible. Finally, we validate the
correctness of the software with cross-checks against
established results within the Standard Model and illustrate
first physical applications that are affected by New Physics
scenarios to demonstrate the potential of $\mathtt{history}$
as a versatile tool for fully-differential cross-section
computations with high precision.},
