Two-photon exchange corrections to elastic $e^{-}$ -proton scattering: Full dispersive treatment of $π N$ states at low momentum transfers

O. Tomalak, B. Pasquini, M. Vanderhaeghen

We evaluate the pion-nucleon intermediate-state contribution to the two-photon exchange (TPE) correction in the elastic electron-nucleon scattering within a dispersive framework. W…

Precision Measurement of the W-Boson Mass: Theoretical Contributions and Uncertainties

Carlo Michel Carloni Calame, Mauro Chiesa, Homero Martinez +4

We perform a comprehensive analysis of electroweak, QED and mixed QCD-electroweak corrections underlying the precise measurement of the W-boson mass M_W at hadron colliders. By app…

The fourth dimension of the nucleon structure: spacetime analysis of the timelike electromagnetic proton form factors

Andrea Bianconi, Egle Tomasi-Gustafsson

As well known, spacelike proton form factors expressed in the Breit frame may be interpreted as the Fourier transform of static space distributions of electric charge and current.…

Determining the CP nature of spin-0 mediators in associated production of dark matter and $t t ˉ$ pairs

Ulrich Haisch, Priscilla Pani, Giacomo Polesello

In the framework of spin-0 $s$ -channel simplified models, we explore the possibility of assessing the structure of dark matter interactions through the associate production of dark…

Monojet searches for momentum-dependent dark matter interactions

Daniele Barducci, Aoife Bharucha, Nishita Desai +6

We consider minimal dark matter scenarios featuring momentum-dependent couplings of the dark sector to the Standard Model. We derive constraints from existing LHC searches in the m…

Gluon fusion contribution to $H B B$ ( $B = H, γ, Z$ ) at the LHC

Ambresh Shivaji, Pankaj Agrawal, Debashis Saha

We have calculated one-loop amplitudes for the production of Higgs boson in association with two electroweak bosons ( $H, γ, Z$ ) via gluon-gluon fusion. We present preliminary results…

A new $G$ -parity violating amplitude in the $J / ψ$ decay?

R. Baldini Ferroli, F. De Mori, M. Destefanis +25

The $J / ψ$ meson has negative $G$ -parity so that, in the limit of isospin conservation, its decay into $π^{+} π^{-}$ should be purely electromagnetic. However, the measured branching fra…

Revisiting the equivalence of light-front and covariant QED in the light-cone gauge

Luca Mantovani, Barbara Pasquini, Xiaonu Xiong +1

We discuss the equivalence between light-front time-ordered-perturbation theory and covariant quantum field theory in light-front quantization, in the case of quantum electrodynami…

Reconstructing parton densities at large fractional momenta

Alessandro Bacchetta, Marco Radici, Barbara Pasquini +1

Parton distribution functions (PDFs) are nonperturbative objects defined by nonlocal light-cone correlations. They cannot be computed directly from Quantum Chromodynamics (QCD). Us…

Relativistic correction to gluon fragmentation function into pseudoscalar quarkonium

Xiangrui Gao, Yu Jia, LiuJi Li +1

Inspired by the recent measurements of the $η_{c}$ meson production at LHC, we investigate the relativistic correction effect for the fragmentation function of the gluon into $η_{c}$ ,…

Asymmetries in Heavy Quark Pair and Dijet Production at an EIC

Daniël Boer, Piet J. Mulders, Cristian Pisano +1

Asymmetries in heavy quark pair and dijet production in electron-proton collisions allow studies of gluon TMDs in close analogy to studies of quark TMDs in semi-inclusive DIS. Here…

Mono-jet Signatures of Gluphilic Scalar Dark Matter

Rohini M. Godbole, Gaurav Mendiratta, Ambresh Shivaji +1

A gluphilic scalar dark matter (GSDM) model has recently been proposed as an interesting vision for WIMP dark matter communicating dominantly with the Standard Model via gluons. We…

Unraveling the CP phase of top-Higgs coupling in associated production at the LHC

Saurabh D. Rindani, Pankaj Sharma, Ambresh Shivaji

We study the sensitivity of top polarization observables to the CP phase $ζ_{t}$ in the top Yukawa coupling in the process $pp \to t hj$ at the 14 TeV high-luminosity run of the Large…

Transverse pion structure beyond leading twist in constituent models

C. Lorcé, B. Pasquini, P. Schweitzer

The understanding of the pion structure as described in terms of transverse-momentum dependent parton distribution functions (TMDs) is of importance for the interpretation of curre…

Exploring universality of transversity in proton-proton collisions

Marco Radici, Alessandro M. Ricci, Alessandro Bacchetta +1

We consider the azimuthal correlations of charged hadron pairs with large total transverse momentum and small relative momentum, produced in proton-proton collisions with one trans…

Proper definition and evolution of generalized transverse momentum distributions

Miguel G. Echevarria, Ahmad Idilbi, Koichi Kanazawa +4

We consider one of the most fundamental sets of hadronic matrix elements, namely the generalized transverse momentum distributions (GTMDs), and argue that their existing definition…
