Searches for charge-parity (CP) violating interactions of the Standard Model (SM) Higgs boson are a key priority of the LHC physics program. Experimental results from ATLAS and CMS…

Neutron stars can shine a light on elusive lepton-flavor-violating dark matter

Hooman Davoudiasl, Jaime Hoefken Zink, Sebastian Trojanowski

We investigate a scenario in which dark matter (DM) poses a challenge to conventional direct and indirect detection, making it much more elusive than typical candidates. We focus o…

Peter B. Denton, Stephen J. Parke

Algorithms for computing neutrino oscillation probabilities in sharply varying matter potentials such as the Earth are becoming increasingly important. As the next generation of ex…

Cosmic Overture Echoed in a Stellar Final Act: Implications of Nanohertz Gravitational Waves for Core Collapse Supernova Neutrinos

Hooman Davoudiasl, Peter B. Denton, Anna M. Suliga

The growing evidence for nanohertz gravitational waves, from NANOGrav and other observations, may be pointing to a cosmological first-order phase transition at temperatures of $\ma…

Thermal nature of confining strings

We investigate the quantum statistical properties of the confining string connecting a static fermion-antifermion pair in the massive Schwinger model. By analyzing the reduced dens…

New opportunities for rare charm from $Z \to c c ˉ$ decays

Angelo Di Canto, Tabea Hacheney, Gudrun Hiller +4

We analyze the potential of rare charm decays as probes of new physics at a high-luminosity flavor facility operating at the $Z$ pole, such as the FCC-ee or CEPC. In particular, we…

Small $x$ behavior in QCD from maximal entanglement and conformal invariance

Sebastian Grieninger, Kun Hao, Dmitri E. Kharzeev +1

Recent evidence suggests that, at small Bjorken $x$ , QCD evolution drives the proton into a state of maximal entanglement. If the evolution kernel is assumed to be conformally inva…

Nuclear Cold QCD: Review and Future Strategy

F. Arleo, P. Caucal, A. Deshpande +12

Updated Constraints from Electric Dipole Moments in the MSSM with R-Parity Violation

Wolfgang Altmannshofer, P. S. Bhupal Dev, Amarjit Soni +1

We revisit the electric dipole moments (EDMs) of quarks and leptons in the Minimal Supersymmetric Standard Model (MSSM) with trilinear $R$ -parity violation (RPV). In this framework…

Thermal modifications of mesons and energy-energy correlators from real-time simulations of a $U (1)$ lattice gauge theory

João Barata, David Frenklakh, Swagato Mukherjee

We investigate thermal properties of a $U (1)$ lattice gauge theory in $1 + 1$ -dimensions through real-time simulations. We extract the spectral functions directly coupling to the pse…

Global Bayesian Analysis of $J / ψ$ Photoproduction on Proton and Lead Targets

Heikki Mäntysaari, Hendrik Roch, Farid Salazar +3

We perform a global Bayesian analysis of diffractive $J / ψ$ production in $γ + p$ and $γ + Pb$ collisions using a color glass condensate (CGC) based calculation framew…

Regularization Prescription for the Mixing Between Nonlocal Gluon and Quark Operators

Yao Ji, Zhuoyi Pang, Fei Yao +1

It is well-known that in the study of mixing between nonlocal gluon and quark bilinear operators there exists an ambiguity when relating coordinate space and momentum space results…

Numerical Calculation of Coulomb Corrections in Forward Elastic $p^{↑} p$ and $p^{↑} A$ Scattering

Andrei Poblaguev

The analysis of RHIC hydrogen gas jet target polarimeter measurements of transverse analyzing powers $A_{N} (t)$ in proton-nucleus scattering requires accurate Coulomb correcti…

Directed flow from parton spin-orbit coupling in $pp$ and $p A$ collisions

Sanjin Benić, Yoshitaka Hatta

We point out a novel mechanism to generate $cos ϕ$ two-particle azimuthal correlation (`directed flow') in unpolarized proton-proton and proton-nucleus collisions in the forward r…

Physics with high-luminosity proton-nucleus collisions at the LHC

D. d'Enterria, C. A. Flett, I. Grabowska-Bold +29

The physics case for the operation of high-luminosity proton-nucleus ( $p A$ ) collisions during Run 3 and 4 at the LHC is reviewed. The collection of $O$ (1-10 pb $^{- 1}$ ) of…
