We revisit the decay rate of the electroweak vacuum in the Standard Model with the full one-loop prefactor. We focus on the gauge degrees of freedom and derive the degeneracy factors appearing in the functional determinant using group theoretical arguments. … Read More

Journal Club on WZW terms without anomalies: generalised symmetries in chiral Lagrangians (arXiv:2407.20340)Abstract:We consider a 4d non-linear sigma model on the coset $(text{SU}(N)_L times text{SU}(N)_R times text{SU}(2))/(text{SU}(N)_{L+R}times text{U})cong text{SU}(N) times S^2$, that features a topological Wess--Zumino--Witten (WZW) term whose curvature … Read More

Speakers: Nataša Adžič (Institute of Physics, Belgrade)  Studying static properties of colloidal suspensions is often a computationally expensive task due to their complex composition and interactions that appear at various length scales. Large macromolecules are surrounded by small solute particles … Read More

Dark-showers offer a compelling collider signature for Hidden Valley models featuring a confining dark sector. Our work extends the investigation of these models to near-conformal theories where the running coupling, controlled by renormalization group equations (RGE), flows near to an … Read More

We study reported deviations between observations and theoretical predictions associated with the production of a pair of di-leptonically decaying top quarks at the LHC, and we examine the possibility that they reflect a signal of toponium formation. We investigate the … Read More

We have demonstrated for the first time that soap bubbles can be used as lasers. Soap bubbles are simple, yet very unique and marvelous objects. They are very interesting to the wide audience, from children of all ages, to researchers … Read More

I will present the lattice results and underlying formalism on resonances omega and a1 that both strongly decay to three-hadron state pi-pi-pi. These are the first and only two resonances extracted from a three-hadron decay on lattice so far.    … Read More

Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic fluorinated organic compounds that are indispensable in various applications, from consumer products to scientific research, due to their unique chemical and physical properties. Recently, these compounds have been found to … Read More
