Resummation and renormalization of kinematical effects in inclusive P-wave quarkonium production
Journal of High Energy Physics, 2023 We investigate the renormalization properties of the shape function formalism for inclusive production of P-wave heavy quarkonia, which arises from resumming a class of corrections coming from kinematical effects associated with the motion of the heavy ...

Journal of High Energy Physics, 2023 We derive the causality and unitarity constraints on dimension 6 and dimension 8 Gluon field strength operators in the Standard Model Effective Field Theory (SMEFT). In the first part of the paper, we use the ‘amplitude analysis’ i.e. dispersion relation

Resolution of the LHCb η c anomaly
Journal of High Energy Physics, 2023 Due to the heavy-quark symmetry of Non-Relativistic Quantum Chromodynamics (NRQCD), the cross-section for the production of η c can be predicted. This NRQCD prediction when confronted with data from the LHCb is seen to fail miserably.

Inclusive J/ψ photoproduction at the ILC within the framework of non-relativistic QCD
Journal of High Energy Physics, 2022 Based on the non-relativistic quantum chromodynamics factorization framework, we study the inclusive J/ψ photoproduction at the future high energy e + e − collider, International Linear Collider(ILC), where the initial photons come from the back ...

Renormalon subtraction in OPE by dual space approach: nonlinear sigma model and QCD
Journal of High Energy Physics, 2023 It is becoming more important to subtract renormalons efficiently from perturbative calculations, in order to achieve high precision QCD calculations. We propose a new framework “Dual Space Approach” for renormalon separation, which enables subtraction ...

Bell violation in 2 → 2 scattering in photon, gluon and graviton EFTs
Journal of High Energy Physics, 2023 In this paper, we explore Bell inequality violation for 2 → 2 scattering in Effective Field Theories (EFTs) of photons, gluons, and gravitons. Using the CGLMP Bell parameter (I 2), we show that, starting from an appropriate initial non-product state, the

Amplitude/operator basis in chiral perturbation theory
Journal of High Energy Physics, 2023 We establish a systematic construction of the on-shell amplitude/operator basis for Chiral Perturbation Theory (ChPT) in D = 4 spacetime dimensions and with an arbitrary number of flavors N f .

Journal of High Energy Physics, 2022 In large-momentum effective theory (LaMET), the transverse-momentum-dependent (TMD) light-front wave functions and soft functions can be extracted from the simulation of a four-quark form factor and equal-time correlation functions.

Systematic parametrization of the leading B-meson light-cone distribution amplitude
Journal of High Energy Physics, 2022 We propose a parametrization of the leading B-meson light-cone distribution amplitude (LCDA) in heavy-quark effective theory (HQET). In position space, it uses a conformal transformation that yields a systematic Taylor expansion and an integral bound ...

Journal of High Energy Physics, 2022 The non-Gaussian fluctuations of baryon density are sensitive to the presence of the conjectured QCD critical point. Their observational consequences are crucial for the ongoing experimental search for this critical point through the beam energy scan ...
