We obtained constraints on a 12 parameter extended cosmological scenario including non-phantom dynamical dark energy ( NPDDE ) with CPL parametrization .
We also include the six \Lambda CDM parameters , number of relativistic neutrino species ( N _ { \textrm { eff } } ) and sum over active neutrino masses ( \sum m _ { \nu } ) , tensor-to-scalar ratio ( r _ { 0.05 } ) , and running of the spectral index ( n _ { run } ) .
We use CMB Data from Planck 2015 ; BAO Measurements from SDSS BOSS DR12 , MGS , and 6dFS ; SNe Ia Luminosity Distance measurements from the Pantheon Sample ; CMB B-mode polarization data from BICEP2/Keck collaboration ( BK14 ) ; Planck lensing data ; and a prior on Hubble constant ( 73.24 \pm 1.74 km/sec/Mpc ) from local measurements ( HST ) .
We have found strong bounds on the sum of the active neutrino masses .
For instance , a strong bound of \sum m _ { \nu } < 0.123 eV ( 95 % C.L . )
comes from Planck+BK14+BAO .
Although we are in such an extended parameter space , this bound is stronger than a bound of \sum m _ { \nu } < 0.158 eV ( 95 % C.L . )
obtained in \Lambda \textrm { CDM } + \sum m _ { \nu } with Planck+BAO .
Varying A _ { \textrm { lens } } instead of r _ { 0.05 } however leads to weaker bounds on \sum m _ { \nu } .
Inclusion of the HST leads to the standard value of N _ { \textrm { eff } } = 3.045 being discarded at more than 68 % C.L. , which increases to 95 % C.L .
when we vary A _ { \textrm { lens } } instead of r _ { 0.05 } , implying a small preference for dark radiation , driven by the H _ { 0 } tension .
