Associated production of a top quark pair with a heavy electroweak gauge boson at NLO+NNLL accuracy

Anna Kulesza, Leszek Motyka, Daniel Schwartländer +2

We perform threshold resummation of soft gluon corrections to the total cross sections and the invariant mass distributions for production of a top-antitop quark pair associated wi…

Forward Drell-Yan and backward jet production as a probe of the BFKL dynamics

Krzysztof Golec-Biernat, Leszek Motyka, Tomasz Stebel

We propose a new process which probes the BFKL dynamics in the high energy proton-proton scattering, namely the forward Drell-Yan (DY) production accompanied by a backward jet, sep…

Showcasing HH production: Benchmarks for the (HL-)LHC

Philipp Basler, Sally Dawson, Christoph Englert +1

Current projections suggest that the LHC will have only limited sensitivity to di-Higgs production in the Standard Model (SM), possibly even after the completion of its high lumino…

Phenomenology of TeV-scale scalar Leptoquarks in the EFT

Shaouly Bar-Shalom, Jonathan Cohen, Amarjit Soni +1

We examine new aspects of leptoquark (LQ) phenomenology using effective field theory (EFT). We construct a complete set of leading effective operators involving SU(2) singlets scal…

Partial compositeness and baryon matrix elements on the lattice

Venkitesh Ayyar, Thomas DeGrand, Daniel C. Hackett +4

Partial compositeness is a mechanism for the generation of fermion masses which replaces a direct Higgs coupling to the fermions by a linear mixing with heavy composite partners. W…

NLO Effects in EFT Fits to Production at the LHC

Julien Baglio, Sally Dawson, Ian M. Lewis

We study the impact of anomalous gauge boson and fermion couplings on the production of pairs at potential future LHC upgrades and estimate the sensitivity at $\sqrt{S}=14…

Bound state properties from the Functional Renormalisation Group

Reinhard Alkofer, Axel Maas, Walid Ahmed Mian +4

We discuss an approach for accessing bound state properties, like mass and decay width, of a theory within the functional renormalisation group approach. An important cornerstone i…

Temperature dependence of : uncertainties from the equation of state

Jussi Auvinen, Kari J. Eskola, Pasi Huovinen +3

We perform a global model-to-data comparison on Au+Au collisions at GeV and Pb+Pb collisions at TeV and TeV, using a 2+1D hydrodynamics model with…

Activating the 4th Neutrino of the 3+1 Scheme

Peter B. Denton, Yasaman Farzan, Ian M. Shoemaker

Non-Standard Interactions (NSI) of neutrinos with matter has received renewed interest in recent years. In particular, it has been shown that NSI can reconcile the solution w…

SMEFT and the Drell-Yan Process at High Energy

S. Dawson, P. P. Giardino, A. Ismail

The Drell-Yan process is a copious source of lepton pairs at high energy and is measured with great precision at the Large Hadron Collider (LHC). Barring any new light particles, b…

The role of leptons in electroweak baryogenesis

Jordy de Vries, Marieke Postma, Jorinde van de Vis

We investigate the role of leptons in electroweak baryogenesis by studying a relatively simple framework inspired by effective field theory that satisfies all Sakharov conditions.…

Single spin asymmetry in forward collisions: Phenomenology at RHIC

Sanjin Benić, Yoshitaka Hatta

We confront the theoretical result of single spin asymmetry (SSA) in forward collisions including the gluon saturation effect with the recent preli…

Measurement of the Triple Higgs Coupling at a HE-LHC

Samuel Homiller, Patrick Meade

The currently unmeasured triple Higgs coupling is one of the strong motivations for future physics programs at the LHC and beyond. A sufficiently precise measurement can lead to qu…

Aligned and Spontaneous Flavor Violation

Daniel Egana-Ugrinovic, Samuel Homiller, Patrick Meade

We present a systematic spurion setup called Aligned Flavor Violation (AFV) that allows for new physics couplings to quarks that are aligned with the Standard Model (SM) Yukawas, b…

Double-slit experiment at fermi scale: coherent photoproduction in heavy-ion collisions

Wangmei Zha, Lijuan Ruan, Zebo Tang +2

The double-slit experiment has become a classic thought experiment, for its clarity in expressing the central puzzle of quantum mechanics -- wave-particle complementarity. Such wav…

Photoproduction of J/ in non-single-diffractive p+p collisions

Zehua Cao, Lijuan Ruan, Zebo Tang +4

Recently, significant enhancements of J/ production at very low transverse momenta were observed by the ALICE and STAR collaboration in peripheral hadronic A+A collisions. The a…

Quark and gluon contributions to the QCD trace anomaly

Yoshitaka Hatta, Abha Rajan, Kazuhiro Tanaka

We show that, in dimensional reguralization in the minimal subtraction scheme, the QCD trace anomaly can be unambiguously decomposed into two parts coming from the renormalized qua…

TMD factorization for dijets + photon production from the dilute-dense CGC framework

Tolga Altinoluk, Renaud Boussarie, Cyrille Marquet +1

We calculate the production of a photon and two jets at forward rapidity in proton-nucleus collisions, within the hybrid dilute-dense framework in the Color Glass Condensate (CGC)…

R-parity Violation and Light Neutralinos at CODEX-b, FASER, and MATHUSLA

Daniel Dercks, Jordy de Vries, Herbi K. Dreiner +1

The operator in R-parity-violating supersymmetry can lead to meson decays to light neutralinos and neutralino decays to lighter mesons, with a long lifetime. Since the h…

Indirect Signs of the Peccei-Quinn Mechanism

Jordy de Vries, Patrick Draper, Kaori Fuyuto +2

In the Standard Model, the renormalization of the QCD vacuum angle is extremely tiny, and small is technically natural. In the general Standard Model effective field theory…
