Since the discovery of the Higgs boson in 2012, the ATLAS and CMS collaborations at the LHC have made precise measurements of a variety of Higgs boson properties, without significant evidence of any BSM behavior. However, large uncertainties are still present on many properties, and many others still remain unmeasured. In this talk, I will summarize the status of Higgs boson measurements and...

We present a calculation of pseudoscalar Higgs production in association with a jet at Next-to-Next-to Leading Order (NNLO) accuracy in QCD. We work in an effective field theory in which $m_t \rightarrow \infty$ resulting in effective operators which couple the pseudoscalar to gluons and (massless) quarks. We have calculated all of the relevant amplitudes for the two-loop, one-loop and...

The impact of finite bottom-quark mass effects at next-to-next-to-leading order constitutes one of the leading theory uncertainties of the Higgs production cross section.

In this talk, I will present our evaluation of this contribution. We computed the relevant two-loop master integrals that enter the real-virtual contribution numerically using the method of differential equations. In...

The calculation and manipulation of large multi-variable rational

functions is a key bottleneck in multi-loop calculations. In this talk I

will present work using p-adic numbers to reconstruct rational functions

in a compact form. I will apply this to examples such as rational

functions appearing in cutting-edge 2-loop 5-point amplitudes calculations.

We review improvements in precision heavy quark production including updates in the xFitter global analysis framework, and extensions of ACOT using fast grid techniques.

I report on the progress in the precision studies of hadronic parton distributions by the CTEQ-TEA (Tung Et Al.) group.

Parton distribution functions (PDFs) are of key interest in both particle and nuclear physics. At the LHC, the limited knowledge of PDFs is currently one of the leading bottlenecks in precise predictions. In nuclear physics, PDFs provide insight into the structure of the nucleon, towards more complicated systems.

In this talk I will first motivate the need for precise PDFs, then explain how...

In this talk I'll present our recent work calculating the N-jettiness soft function, based on an extension of the SoftSERVE framework to the general case of N+2 jets and beams for *a priori* general global observables. I will comment on our approach, present an explicit grid scanning the 2-jettiness soft function, and shed some light on the behaviour of the N-jettiness soft function at the...

I will discuss issues that arise from the mismatch between asymptotic states and partonic states in the formal definitions of fragmentation functions. I will show that standard derivations of common sum rules need to be modified for gauge theories, and discuss several possibilities for constructing more precise definitions. Implications for phenomenological applications will also be discussed.

The MiNNLO framework offers an efficient approach to consistently include NNLO QCD corrections within Monte-Carlo event generators. As the first (and only) NNLO+PS method that was extended beyond colour-singlet production, recent developments of the MiNNLO method will be discussed that tackle new classes of hadron-collider reactions, including heavy quarks, jets, and colour singlets in the...

The general mass variable flavor number (GMVFN) scheme S-ACOT-MPS will

be discussed for proton-proton collisions. The impact of heavy-flavor

contributions within this factorization scheme will be shown for the production

of a $Z$ boson in association with a charm/bottom quark in pQCD.

An amended version of the QCD factorization formula for proton-proton collisions will

be discussed as...

We present results from a global fit of dimension-six SMEFT operators that includes electroweak, Higgs-boson, top-quark, and flavor observables. The leading-order scale dependence of the SMEFT Wilson

coefficients is consistently included in the evolution from the UV

scale to the electroweak scale and the low-energy scale of flavor

observables. The global fit is obtained within the HEPfit...

A TeV muon-ion collider could be established if a high energy muon beam that is appropriately cooled and accelerated to the TeV scale is brought into collision with a high energy hadron beam using facilities such as at Brookhaven National Lab, Fermilab, or CERN. Such a collider opens up a new regime for deep inelastic scattering studies as well as facilitates precision QCD and electroweak...

Parton shower event generators are essential tools for establishing the quantitative connection between theory and experiment. However, their flexibility comes with a trade-off: they generally offer lower formal accuracy compared to state-of-the-art analytic calculations, which in turn have more limited applicability. The poor accuracy of the inevitably employed parton shower generators...

The GENEVA method provides a means to combine resummed and fixed order calculations at state-of-the-art accuracy with a parton shower program. GENEVA NNLO+PS generators have now been constructed for a range of colour-singlet production processes and using a range of different resolution variables. I will review the GENEVA framework and then describe several recent advancements, such as the use...
