All physical processes can be described, at a fundamental level, through interactions of elementary particles. The Standard Model of particle physics (SM) describes three of the four known fundamental forces and all of the known elementary particles. The a ...

A search for the very rare

Six C-even states, denoted as X, with quantum numbers J(PC) = 0(-+), 1(++), or 2(++), are searched for via the e(+)e(-) -> gamma(DsDs*-/+)-D-+/- process using (1667.39 +/- 8.84) pb(-1) of e(+)e(-) collision data collected with the BESIII detector operating ...

We search for the hadronic decay eta(c)(2S) -> 2(pi(+) pi(-)) in the psi(3686) -> gamma eta(c)(2S) radiative decay using (27.12 +/- 0.14) x 10(8) psi(3686) events collected by the BESIII detector at the BEPCII collider. No significant signal is found, and ...

The first search for the lepton number violating decay K+→π0π−μ+e+ and lepton flavour violating decays K+→π0π+μ−e+, K+→π0π+μ+e− has been performed using a dataset collected by the NA62 experiment at CERN in 2016–2018. Upper limits of 2.9×10−10, 3.1×10−10 a ...

The lattice studies provided evidence of a smooth crossover between the hadronic and quark-gluon phases at high temperatures and zero chemical potential for baryonic number. We argue that these simulations may not rule out relatively weekly first-order pha ...

The production of prompt Lambda(+)(c) baryons is measured via the exclusive decay channel Lambda(+)(c) -> pK(-) pi(+) at a center-of-mass energy per nucleon pair of 5.02TeV, using proton-proton (pp) and lead-lead (PbPb) collision data collected by the CMS ...

This thesis links two realms of particle accelerator dynamics and precision particle physics. The achievement of precise luminosity measurement at hadron colliders is enabled with dedicated luminometers. For the Run 3 period, the luminometer upgrade was ...

The Universe may contain sufficiently small size matter-antimatter domains at temperatures of a few hundred MeV, without violating the success of big bang nucleosynthesis. We demonstrate that this possibility enhances the keV scale sterile neutrino product ...

Using (10087 +/- 44) x 10(6) J/psi events collected with the BESIII detector, we search for the rare decay J/psi -> gamma D-0 + c.c. for the first time. No significant signal is observed and the upper limit on the branching fraction is determined to be B(J ...
