Determination of F_pi from Distributions of Dirac Operator Eigenvalues with Imaginary Density [PDF]

, 2007
In the epsilon-regime of lattice QCD one can get an accurate measurement of the pion decay constant F_pi by monitoring how just one single Dirac operator eigenvalue splits into two when subjected to two different external vector sources.

Heavy quark physics on the lattice with improved nonrelativistic actions [PDF]

, 2010
Hadrons containing heavy quarks, in particular b quarks, play an important role in high energy physics. Measurements of their electroweak interactions are used to test the Standard Model and search for new physics.

Lattice Quantum ChromoDynamics with approximately chiral fermions [PDF]

, 2008
In this work we present Lattice QCD results obtained by approximately chiral fermions. We use the CI fermions in the quenched approximation to investigate the excited baryon spectrum and to search for the Theta^+ pentaquark on the lattice. Furthermore we

Neutrino Mass, Coupling Unification, Verifiable Proton Decay, Vacuum Stability, and WIMP Dark Matter in SU(5)

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
Nonsupersymmetric minimal SU(5) with Higgs representations 24H and 5H and standard fermions in 5¯F⊕10F is well known for its failure in unification of gauge couplings and lack of predicting neutrino masses. Like standard model, it is also affected by the instability of the Higgs scalar potential.

Lattice investigation of the tetraquark candidates a0(980) and kappa [PDF]

, 2012
It is a long discussed issue whether light scalar mesons have sizeable four-quark components. We present an exploratory study of this question using Nf = 2+1+1 twisted mass lattice QCD.

Microscopic unitary description of tidal excitations in high-energy string-brane collisions [PDF]

, 2013
The eikonal operator was originally introduced to describe the effect of tidal excitations on higher-genus elastic string amplitudes at high energy.

Regge behavior saves string theory from causality violations [PDF]

, 2015
Higher-derivative corrections to the Einstein-Hilbert action are present in bosonic string theory leading to the potential causality violations recently pointed out by Camanho et al.
