Dark Spectroscopy

, 2017
Rich and complex dark sectors are abundant in particle physics theories. Here we propose performing spectroscopy of the mass structure of dark sectors via mono-photon searches at lepton colliders.

Modified Lüscher zeta-function and the modified effective range expansion in the presence of a long-range force

Journal of High Energy Physics
An efficient numerical algoritm is proposed for the calculation of the modified Lüscher zeta-function in the presence of a long-range force. Using the formalism developed in ref.

Hadrons and Nuclei

, 2019
This document is one of a series of whitepapers from the USQCD collaboration. Here, we discuss opportunities for lattice QCD calculations related to the structure and spectroscopy of hadrons and nuclei.

Strange Quarkonium States at BESIII

, 2015
We present physics opportunities and topics with the $s\bar{s}$ states (strangeonia) that can be studied with the BESIII detector operating at the BEPCII collider. Though the $\phi$ and $\eta/\eta^\prime$ states have long been established experimentally,

The hadronic vacuum polarization contribution to the muon g − 2 at long distances

Journal of High Energy Physics
We present our lattice QCD result for the long-distance part of the hadronic vacuum polarization contribution, ( a μ hvp $$ {a}_{\mu}^{\textrm{hvp}} $$ )LD, to the muon g − 2 in the time-momentum representation.

Hard hadron spectroscopy [PDF]

Proceedings of The XXV International Symposium on Lattice Field Theory — PoS(LATTICE 2007), 2008
22 pages, 10 figures, plenary talk presented at the XXV International Symposium on Lattice Field Theory, 30 July - 4 August 2007, Regensburg, Germany. Changed the discussion of preliminary results for a0 and b1 masses from ETMC, because of an error in the analysis found while preparing arXiv:0906 ...

Evolution of parton distribution functions in the short-distance factorization scheme

Journal of High Energy Physics
Lattice QCD offers the possibility of computing parton distributions from first principles, although not in the usual MS ¯ $$ \overline{MS} $$ factorization scheme.

The Chiral Restoration Transition of QCD and Low Mass Dileptons

, 2009
Recent developments in the evaluation of vector-meson spectral functions in hot and dense matter are discussed with emphasis on connections to the chiral phase transition in QCD.

Quark transverse spin-momentum correlation of the nucleon from lattice QCD: the Boer-Mulders function

Journal of High Energy Physics
We present the first lattice QCD calculation of the quark transverse spin-momentum correlation, i.e., the naive time-reversal-odd Boer-Mulders function, of the nucleon, using large-momentum effective theory (LaMET).

Physics of Ultra-Relativistic Nuclear Collisions with Heavy Beams at LHC Energy

, 1999
We discuss current plans for experiments with ultra-relativistic nuclear collisions with heavy beams at LHC energy ($\sqrt{s} = 5.5$ TeV/nucleon pair). Emphasis will be placed on processes which are unique to the LHC program.
