STAR highlights on heavy ion physics

open access: yesEPJ 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

open access: yesJournal 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 ...

Apparent unitarity violation in high mass region of MbW from a “hidden” top partner at high energy colliders

open access: yesPhysics Letters B, 2016
Perturbative unitarity conditions have been playing an important role in estimating the energy scale of new physics, including the Higgs mass as the most important example.

Measurement of the top quark charge in pp collisions at s√=7 TeV with the ATLAS detector [PDF]

open access: yes, 2013
A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb−1 of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined

Intrinsic bottom and its impact on heavy new physics at the LHC

open access: yesEPJ 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

open access: yesEPJ 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

open access: yesJournal 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

LHCb Overview [PDF]

open access: yesEPJ Web of Conferences
The LHCb experiment has a complete heavy ion physics program, including studies of pp, pA, AA, and UPC events delivered by the Large Hadron Collider, along with a rapidly expanding fixed-target capability. With unique acceptance and detector capabilities,

|Vub| determination and testing of lepton flavour universality in semileptonic Bc → D(∗) decays

open access: yesJournal of High Energy Physics, 2020
In light of prospects for measurements of B c  → D (∗) lv decays in the upcoming Upgrade II of the LHC, we show that by using calculated B c  → D (∗) form factors a competitive extraction of the |V ub | CKM matrix element from the B c → Dμ v ¯ μ $$ {B}_c\
