Prompt neutrinos and intrinsic charm at SHiP
Journal of High Energy Physics, 2019 We present a new evaluation of the far-forward neutrino plus antineutrino flux and number of events from charm hadron decays in a 400 GeV proton beam dump experiment like the Search for Hidden Particles (SHiP).

Heavy quark physics on the lattice [PDF]
Nuclear Physics B - Proceedings Supplements, 2001 I review the current status of lattice calculations of the properties of bound states containing one or more heavy quarks. Many of my remarks focus on the heavy-light leptonic decay constants, such as $f_B$, for which the systematic errors have by now been quite well studied. I also discuss $B$-parameters, semileptonic form factors, and the heavy-light

A self-consistent framework of topological amplitude and its SU(N) decomposition
Journal of High Energy Physics, 2021 We propose a systematic theoretical framework for the topological amplitudes of the heavy meson decays and their SU(N) decomposition. In the framework, the topologies are expressed in invariant tensors and classified into tree- and penguin-operator ...

STAR highlights on heavy ion physics
EPJ Web of Conferences, 2015 RHIC-STAR is a mid-rapidity collider experiment for studying high energy nuclear collisions. The main physics goals of STAR experiment are 1) studying the properties of the strongly coupled Quark Gluon Plasma 2) explore the QCD phase diagram structure ...

From topological amplitude to rescattering dynamics
Journal of High Energy Physics, 2022 We proposed a theoretical framework to correlate the topological diagram at quark level and rescattering dynamics at hadron level. In the framework, both the hadronic triangle diagram, and the topological-scattering diagram, which is the intermediate ...

Intrinsic bottom and its impact on heavy new physics at the LHC
EPJ Web of Conferences, 2016 Heavy quark parton distribution functions (PDFs) play an important role in several Standard Model and New Physics processes. Most analyses rely on the assumption that the charm and bottom PDFs are generated perturbatively by gluon splitting and do not ...

Classical gluon production amplitude in heavy-ion collisions
EPJ Web of Conferences, 2016 The initial condition for the formation of the Quark-Gluon Plasma, the distribution of quarks and gluons produced in the initial stages of nuclear collisions, is the fundamental building block of heavy-ion theory.

The static hard-loop gluon propagator to all orders in anisotropy
Journal of High Energy Physics, 2017 We calculate the (semi-)static hard-loop self-energy and propagator using the Keldysh formalism in a momentum-space anisotropic quark-gluon plasma. The static retarded, advanced, and Feynman (symmetric) self-energies and propagators are calculated to all
