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

Joshua Lockyer: Exploring near-conformal dark sector theories

https://zoom.us/j/3601731049?pwd=bVNQRjUxU2ExZ0cveWcxYXNUUGdjZz09 (A/1-106 - Seminarska soba fizike (F5))

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

Benjamin Fuks: Signatures of toponium formation in LHC run 2 data

https://zoom.us/j/3601731049?pwd=bVNQRjUxU2ExZ0cveWcxYXNUUGdjZz09 (Jamova)

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

Zala Korenjak, “Smectic and soap bubble optofluidic lasers”

Seminar room of physics (106) (IJS)

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

Maxim Mai: Lattice studies of resonances that decay to three-hadrons

https://zoom.us/j/3601731049?pwd=bVNQRjUxU2ExZ0cveWcxYXNUUGdjZz09 (A/1-106 - Seminarska soba fizike (F5))

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

Katarina Kokalj, “Structural analysis of partially fluorinated liquid ethanol”

A/1-106 - Seminarska soba fizike (F5) (Jamova)

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

Emanuela Bianchi, “Modeling and simulating heterogeneously charged particles: from materials design to biological phenomena”

Seminar room of physics (106) (IJS)

Globular proteins and recently synthesized colloids engineered with differently charged surface regions share a direction-dependent interaction characterized by a reduced bonding valence and a competition between like-charge attraction and opposite-charge repulsion. Understanding the large-scale behavior of heterogeneously charged particles is … Read More
