A signature invariant geometric algebra framework for spacetime physics and its applications in relativistic dynamics of a massive particle and gyroscopic precession [PDF]
Scientific Reports, 2022 A signature invariant geometric algebra framework for spacetime physics is formulated. By following the original idea of David Hestenes in the spacetime algebra of signature $$(+,-,-,-)$$ ( + , - , - , - ) , the techniques related to relative vector and ...

Dressing vs. Fixing: On How to Extract and Interpret Gauge-Invariant Content. [PDF]
Found PhysThere is solid consensus among physicists and philosophers that, in gauge field theory, for a quantity to be physically meaningful or real, it must be gauge-invariant.

Interacting Two-Time Physics Field Theory With a BRST Gauge Invariant Action [PDF]
, 2006 We construct a field theoretic version of 2T-physics including interactions in an action formalism. The approach is a BRST formulation based on the underlying Sp(2,R)gauge symmetry, and shares some similarities with the approach used to construct string ...

SPIN: SE(3)-Invariant Physics Informed Network for Binding Affinity Prediction [PDF]
European Conference on Artificial IntelligenceAccurate prediction of protein-ligand binding affinity is crucial for rapid and efficient drug development. Recently, the importance of predicting binding affinity has led to increased attention on research that models the three-dimensional structure of ...

Top Quark Pairs at High Invariant Mass - A Model-Independent Discriminator of New Physics at the LHC [PDF]
, 2006 We study top quark pair production to probe new physics at the LHC. We propose reconstruction methods for $t\bar{t}$ semileptonic events and use them to reconstruct the $t\bar{t}$ invariant mass. The angular distribution of top quarks in their c.m. frame

Scale-invariant resonance tagging in multijet events and new physics in Higgs pair production [PDF]
Journal of High Energy Physics, 2013 A bstractWe study resonant pair production of heavy particles in fully hadronic final states by means of jet substructure techniques. We propose a new resonance tagging strategy that smoothly interpolates between the highly boosted and fully resolved ...

Invariant representation of physical stability in the human brain [PDF]
eLife, 2021 Successful engagement with the world requires the ability to predict what will happen next. Here we investigate how the brain makes the most basic prediction about the physical world: whether the situation in front of us is stable, and hence likely to ...
