Revisiting Single Inclusive Jet Production: Small- $R$ Resummation at Next-to-Leading Logarithm
Kyle Lee🇺🇸 · Ian Moult🇺🇸 · Xiaoyuan Zhang🇺🇸
The precision description of jet production plays an important role in many aspects of collider physics. In a recent paper we have presented a new factorization theorem for inclusive small radius jet production. The jet function appearing in our factorization theorem exhibits a non-standard renormalization group evolution, which, starting at next-to-leading logarithm (NLL), differs from previous results in the literature. In this paper we perform a first phenomenological study using our newly developed formalism, applying it to compute the spectrum of small radius jets in $e^{+} e^{-} \to J + X$ at NLL. We compare our results with previous predictions, highlighting the numerical impact of previously neglected terms throughout phase space. Our approach can be used for a variety of different collider systems, in particular, $e p$ and $pp$ collisions, with broad applications to the jet substructure program. Most importantly, since our factorization theorem is valid to all orders, the approach developed here will enable NNLL resummation of small radius logarithms in inclusive jet production, extending the precision of jet substructure calculations.

Gravitational form factors of glueballs in Yang-Mills theory
Ryan Abbott🇺🇸 · Daniel C. Hackett🇺🇸 · Dimitra A. Pefkou🇺🇸 · Fernando Romero-López🇨🇭 · Phiala Shanahan🇺🇸
This work presents preliminary results of the first determination of the energy-momentum tensor form factors of the scalar glueball, referred to as gravitational form factors (GFFs). The calculation has been carried out in lattice Yang-Mills theory at a single lattice spacing. Using variationally optimized operators, the matrix elements are extracted from ratios of three-point functions to two-point functions. The glueball GFFs and their kinematic dependence are compared to those of other hadrons from previous calculations.

Transverse Energy-Energy Correlator for Vector Boson-Tagged Hadron Production in $pp$ and $p A$ collisions
Zhong-Bo Kang🇺🇸 · Sookhyun Lee🇺🇸 · Jani Penttala🇺🇸 · Fanyi Zhao🇺🇸 · Yiyu Zhou🇺🇸
We investigate the transverse energy-energy correlator (TEEC) event-shape observable for back-to-back $γ + h$ and $Z + h$ production in both $pp$ and $p A$ collisions. Our study incorporates nuclear modifications into the transverse-momentum dependent (TMD) factorization framework, with resummation up to next-to-leading logarithmic (NLL) accuracy, for TEEC as a function of the variable $τ = (1 + cos ϕ) /2$ , where $ϕ$ is the azimuthal angle between the vector boson and the final hadron. We analyze the nuclear modification factor $R_{p A}$ in $p Au$ collisions at RHIC and $p Pb$ collisions at the LHC. Our results demonstrate that the TEEC observable is a sensitive probe for nuclear modifications in TMD physics. Specifically, the changes in the $τ$ -distribution shape provide insights into transverse momentum broadening effects in large nuclei, while measurements at different rapidities allow us to explore nuclear modifications in the collinear component of the TMD parton distribution functions in nuclei.
