QCD Thermodynamics with an almost realistic quark mass spectrum [PDF]
, 2005 We will report on the status of a new large scale calculation of thermodynamic quantities in QCD with light up and down quarks corresponding to an almost physical light quark mass value and a heavier strange quark mass.

New limits on light scalar and pseudoscalar particles produced in nuclear decay [PDF]
Physical Review D, 1988 We present the results of a search for scalar and pseudoscalar particles produced in nuclear deexcitation. Measurements of the angular correlation of e+e- pairs emitted from excited states of 14N, 16O, and 8Be provided sensitivity to particles with lifetimes 10^-19 < τ < 10^-11 s within the mass range 2me < MX < 5 MeV.

Probing R-parity violation in B-meson decays to a baryon and a light neutralino
Journal of High Energy Physics, 2023 We propose a search for B meson decays to a baryon plus missing energy at the Belle II experiment to probe supersymmetry with a GeV-scale lightest neutralino χ ~ 1 0 $$ {\overset{\sim }{\chi}}_1^0 $$ and R-parity violation (RPV).

Motion and collision of particles near DST Black holes
, 2019 We consider Deser-Sarioglu-Tekin (DST) black holes as background and we study such the motion of massive particles as the collision of two spinning particles in the vicinity of its horizon.

Decoherence for a heavy particle interacting with a light particle: New analysis and numerics [PDF]
Communications in Mathematical Sciences, 2016 We study the dynamics of a quantum heavy particle undergoing a repulsive interaction with a light one. The main motivation is the detailed description of the loss of coherence induced on a quantum system (in our model, the heavy particle) by the interaction with the environment (the light particle). The content of the paper is analytical and numerical.

Invisible Upsilon decays into Light Dark Matter
, 2009 Invisible psi and Upsilon decays into light neutralinos, within the MSSM or N(n)MSSM, are smaller than for nu nubar production, even if light spin-0 particles are coupled to quarks and neutralinos.

Glue to light signal of a new particle
, 2015 Any new particle charged under $SU(3)_C$ and carrying electric charge will leave an imprint in the di-photon invariant mass spectrum as it can mediate $gg \to $ process through loops. The combination of properties of loop functions, threshold resummation and gluon pdfs can result in a peak-like feature in the di-photon invariant mass around twice ...

Bounds on models with one latticized extra dimension [PDF]
, 2003 We study an extension of the standard model with one latticized extra dimension accessible to all fields. The model is characterized by the size of the extra dimension and the number of sites, and contains a tower of massive particles.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Matched detectors as definers of force
, 2004 Although quantum states nicely express interference effects, outcomes of experimental trials show no states directly; they indicate properties of probability distributions for outcomes.
