   Source: hep-th (High Energy Physics - Theory)
   Link: https://arxiv.org/abs/2611.09820

   Source: hep-ph (High Energy Physics - Phenomenology)
   Link: https://arxiv.org/abs/2611.09549
   In analogy to the Kramers-Henneberger transformation in non-relativistic quantum mechanics, we propose and investigate a spinor transformation for the Dirac equation which allows us to transform space-time dependent vector potentials $A(t,x)\boldsymbol{e}$_x away.

   Source: hep-lat (High Energy Physics - Lattice)
   Link: https://arxiv.org/abs/2603.18205
   The Hubbard model at finite chemical potential is a cornerstone for understanding doped correlated systems, but simulations are severely limited by the sign problem.

   Source: hep-ex (High Energy Physics - Experiment)
   Link: https://arxiv.org/abs/2610.41078
   We study the pure annihilation decay $B_c^+ \to ST$ for the first time in the standard model with $S$ and $T$ representing the states of the light scalar ($1^3\!P_0$) and tensor ($1^3\!P_2$) correspondingly.

   We perform a comparison of the Glauber and Trento model predictions for the initial state azimuthal anisotropies $\epsilon_{2,3}\{2\}$ in central Pb+Pb collisions at the LHC energies.
8. Framing Anomaly in Lattice Chern-Simons-Maxwell Theory
   Source: hep-lat (High Energy Physics - Lattice)
   Link: https://arxiv.org/abs/2601.04318
   Framing anomaly is a key property of $(2+1)d$ chiral topological orders, for it reveals that the chirality is an intrinsic bulk property of the system, rather than a property of the boundary between two systems.

   We present a renormalon-subtracted formulation of potential nonrelativistic QCD (pNRQCD) for precision spectroscopy of heavy hadron systems, combining variational and Green's function Monte Carlo (VMC/GFMC) methods with static two- and three-body potentials through NNLO in $\alpha_s$ (leading order in $1/m_Q$).

   This paper considers the self-dual $CP^{N-1}$ model in two dimensions, which is defined by restricting the path integral of the ordinary two-dimensional $CP^{N-1}$ model to holomorphic configurations.
