6. Studying the interactions of charm hadrons with femtoscopy

In the last years, several unconventional hadrons were observed in the charm sector. As such hadrons cannot be explained as 2- or 3-quark states, they are considered to be quark bags or hadron molecules. To unveil their nature it is necessary to constrain the strong nuclear force that governs the interactions of charm hadrons. An excellent tool to achieve this is the femtoscopy technique,...

3. Accessing the strong interaction between Λ baryons and strange hadrons with femtoscopy at LHC

Traditional experimental approaches, such as scattering and hypernuclei measurements, are insufficient to provide stringent constraints to
the theoretical modeling of the interaction between strange hadrons and hence questions on the existence and nature of predicted exotic bound states or resonances are still open.
In the baryon-baryon interaction, this is indeed the case for the...

2. Dynamics of confined monopoles and similarities with confined quarks

Juan Sebastian Valbuena Bermudez (LMU)

We study the annihilation of a pair of ‘t Hooft-Polyakov monopoles due to confinement by a string. We analyze the regime in which the scales of monopoles and strings are comparable. We observe that in a head-on collision, monopoles are never recreated. Correspondingly, not even once the string oscillates. Instead, the system decays into waves of Higgs and gauge fields. We explain this...

4. PID for Hadron Spectroscopy at LHCb

Youhua Yang (Universita di Genova)

Particle identification (PID) efficiency plays a pivotal role in hadron spectroscopy study at hadron colliders, as demonstrated by the substantial increase in efficiency of $\Lambda_b\to J/\psi pK$ in LHCb RUN II compared to RUN I. By introducing PID variables, the signal yield has increased tenfold; five times due to luminosity and an additional two times due to enhanced PID efficiency. In...
