Energy dependence of moments of net-proton multiplicity distributions at RHIC

L Adamczyk, JK Adkins, G Agakishiev, MM Aggarwal… - Physical Review Letters, 2014 - APS
We report the beam energy (s NN= 7.7–200 GeV) and collision centrality dependence of the
mean (M), standard deviation (σ), skewness (S), and kurtosis (κ) of the net-proton multiplicity …

Sign of kurtosis near the QCD critical point

MA Stephanov - Physical Review Letters, 2011 - APS
We point out that the quartic cumulant (and kurtosis) of the order parameter fluctuations is
universally negative when the critical point is approached on the crossover side of the phase …

asymmetries in e+ e-annihilations and semi-inclusive hadron production in deep inelastic …

New approach to the sign problem in quantum field theories:<? format?> High density QCD on a Lefschetz thimble

M Cristoforetti, F Di Renzo, L Scorzato… - Physical Review D …, 2012 - APS
It is sometimes speculated that the sign problem that afflicts many quantum field theories
might be reduced or even eliminated by choosing an alternative domain of integration within …

Probing novel scalar and tensor interactions from (ultra) cold neutrons to the LHC

T Bhattacharya, V Cirigliano, SD Cohen, A Filipuzzi… - Physical Review D …, 2012 - APS
Scalar and tensor interactions were once competitors to the now well-established VA
structure of the standard model weak interactions. We revisit these interactions and survey …

Axial, scalar, and tensor charges of the nucleon from -flavor Lattice QCD

Using higher moments of fluctuations and their ratios in the search for the QCD critical point

C Athanasiou, K Rajagopal, M Stephanov - Physical Review D—Particles …, 2010 - APS
The QCD critical point can be found in heavy-ion collision experiments via the
nonmonotonic behavior of many fluctuation observables as a function of the collision …
